Hello!
I have some page named CallsHospInsert. It have some code:

<apex:page standardController="CallReportHosp__c" extensions="CtrlCallHospInsert" id="CallsHospEditt">
<script type="text/javascript">
function openOrganisationDialog() {
        openPopup("/apex/AccountsListforHosp?context=pharma_chain&list=noList", "lookup", 900, 600, "width=900,height=600,toolbar=no,status=no,directories=no,menubar=no,resizable=yes,scrollable=no", true);
        }
        window.addSelectedOrganisationsIns = function(Organisations) {
            applyFilterByOrganisationsIns(Organisations);}
</script>
    <apex:form >


 <apex:actionfunction name="applyFilterByOrganisationsIns" action="{!applyFilterByOrganisationsIns}" rerender="isorganisation,organisation" status="asLoadingSelectedOrganisations">
            <apex:param name="selectedOrganisationsStr" value="" assignto="{!selectedOrganisationsStr}" />
        </apex:actionfunction>

<apex:pageBlockSectionItem >
                
                    <apex:outputLabel value="Organisation" for="organisation"/>
                    <apex:actionRegion id="isorganisation" >
                    <apex:inputfield value="{!rep.AccountID__c}" id="organisation" required="true" onclick="openOrganisationDialog()">

                    </apex:inputfield>
                    </apex:actionRegion>
                
                </apex:pageBlockSectionItem>

Controller:

public class CtrlCallHospInsert {

public Boolean booleanValue {get;set;}
public CallReportHosp__c rep {get; set;}

public Set<Id> selectedOrganisationsIds  { get; set; }
public String selectedOrganisationsStr { get; set; }

private ApexPages.StandardController controller { get; set; }

    public CtrlCallHospInsert(ApexPages.StandardController controller) {
         this.controller = controller; 
         this.rep = (CallReportHosp__c)controller.getRecord();   
         this.booleanValue=false;       
         System.debug(' bool= '+booleanValue);
         SelectService(); 
    }

public void applyFilterByOrganisationsIns() {
system.debug('apply filter by org');
        this.selectedOrganisationsIds = new Set<Id>();
        if(String.isBlank(this.selectedOrganisationsStr) || this.selectedOrganisationsStr == '[]') {
            return;
        }
        String[] OrganisationsIds = this.selectedOrganisationsStr.remove('[').remove(']').remove(' ').split(',');
        for(String s : OrganisationsIds) {
            if(!String.isBlank(s)) {
                System.debug(' org= '+s );
                rep.AccountID__c=s;
            }
        }
        this.selectedOrganisationsStr = null;
    }

public List<Account> getSelectedOrganisations() {
        Account[] Organisations = [SELECT Name FROM Account WHERE Id IN :this.selectedOrganisationsIds ORDER BY Name];
        return Organisations;
    }

public PageReference save(){
        
        try {
            insert rep;
        }catch (Exception e){
            ApexPages.addmessage(new ApexPages.message(ApexPages.severity.ERROR, '"Something went wrong !"'));
        }
        PageReference pageRef = Page.CallsHospList;
        pageRef.setRedirect(true);
        return pageRef;
    }
    
 public void ChangeField()
 {
 }   
    
 public PageReference cancel() {
        PageReference pageRef = Page.CallsHospList;
        pageRef.setRedirect(true);
        return pageRef;        
    }
    
}

So, when i click on field rep.AccountID__c the page named AccountsListforHosp open. Then I  select organisation name and page AccountsListforHosp  closed. After that I waiting page CallsHospInsert is updating by using method applyFilterByOrganisationsIns(), but method doesn't work.
That code of page AccountsListforHosp :

<apex:column rendered="{!Not(ListCalls)}">
                            <apex:commandLink action="{!updateSelectedAccountsSet}"  onclick="updateSelectedAccountsIns(); return false;"  value="{!res.record.Name}" />
                        </apex:column>
.......


<apex:actionfunction name="updateSelectedAccountsIns" action="{!updateSelectedAccountsSet}" oncomplete="addSelectedOrganisationsIns();" rerender="pnlSearchResults"> 
                                                <apex:param name="bParam" value="{!record.id}" assignTo="{!ArecordId}"/>
                    </apex:actionfunction>
                    <script type="text/javascript">
                        function addSelectedOrganisations() {
                            var searchContext = "{!searchContext}";
                            var parentWindow = top.parent.window;
                            if(searchContext === "brick") {
                                parentWindow.opener.addSelectedBricks("{!selectedRecords}");
                            } else { if (searchContext === "pharma_chain") {
                                parentWindow.opener.addSelectedOrganisations("{!selectedRecords}");}
                                else {parentWindow.opener.addSelectedParents("{!selectedRecords}");}
                            } 
                            parentWindow.close();
                        }
                         function addSelectedOrganisationsIns() {
                            var searchContext = "{!searchContext}";                            
                            var parentWindow = top.parent.window;                            
                            if (searchContext === "pharma_chain") {
                                parentWindow.opener.addSelectedOrganisationsIns("{!selectedRecords}");}                               
                            parentWindow.close();
                        }
                    </script>

And I caused this page with context noList ( Not(ListCalls) = true).
So, why method applyFilterByOrganisationsIns() doesn't starting?
P.S.
Please sorry for my bad English.
