Hi all,
I use radio button in my visualforce page but it's not save.
I try apex:inputCheckbox or apex:inputField and actionsupport it's not working.

this is my visualforce page : 

<apex:page standardController="Quotation_Request__c" extensions="Select_MOQ_Extension" sidebar="false">
    
    <p><apex:sectionHeader title="Select MOQ" subtitle="{!theQuote.Name}"/></p>
    
    <apex:form >
    
        <apex:pageBlock title="Quotation Request Line Item">
        
            <apex:repeat value="{!lstQuoteLine}" var="items">
                
                <p>

                lstQuoteMOQ.add(quoteMOQ);
            
            }
        
        }
        
    }
    
    public void onCheck() {
        
        system.debug('checkMOQ : ' + checkMOQ);
        
        for (Quotation_MOQ__c quoteMOQ : lstQuoteMOQ) {
        
            if ((String)quoteMOQ.Id == checkMOQ) {
            
                quoteMOQ.Selected__c = true;
                //system.debug('quoteMOQ.Selected__c : ' + quoteMOQ.Selected__c);
            
            } else {
            
                quoteMOQ.Selected__c = false;
            
            }
                    
        }
            
    }
    
    public PageReference onSave() {
    
        for (Quotation_MOQ__c quoteMOQ : lstQuoteMOQ) {
            system.debug('quoteMOQ.Selected__c : ' + quoteMOQ.Selected__c);
            if (quoteMOQ.Selected__c == true) {
            
                Quotation_Request_Line_Item__c quoteLine = [select Id, Unit_Price__c, Quantity__c from Quotation_Request_Line_Item__c where Id =: quoteMOQ.Quotation_Request_Line_Item__c];
                quoteLine.Quantity__c = quoteMOQ.Quantity__c;
                quoteLine.Unit_Price__c = quoteMOQ.Price__c;
                
                upsert(quoteLine);
                
            }
        
        }
        
        upsert(lstQuoteMOQ);
        
        String url = '/'+theQuote.Id;

        PageReference pref = new PageReference(url);
