On my VF page I want to be able to only show select fields for USER for editing purposes. I have created this VF page and have the VIEW option at the top with the dropdown based on User Profile. Once I select a different profile and hit the GO button it takes me to the USER page and I want it to rerender my VF page with the type User Profile I selected in the View. 

My theory is that this line of code is what needs to be updated but not positive. 

<apex:actionSupport event="onchange" rerender="user_table"/>

Here is my code. 

<apex:page standardController="User" recordSetVar="users" tabStyle="User">
<apex:form >
<apex:pageBlock >
<apex:pageMessages />
<apex:pageBlock >
<apex:panelGrid columns="2">
<apex:outputlabel value="View:"/>
<apex:selectList value="{!filterId}" size="1">
<apex:actionSupport event="onchange" rerender="user_table"/>
<apex:selectOptions value="{!listviewoptions}"/>
</apex:selectList>
<apex:commandButton value="Go" action="{!list}"/>
</apex:panelGrid>
</apex:pageBlock>

<apex:pageBlockButtons >
<apex:commandButton value="Save" action="{!quicksave}"/>
<apex:commandButton value="Next" action="{!next}"/>
<apex:commandButton value="Previous" action="{!previous}"/>
</apex:pageBlockButtons>

<apex:pageBlockTable value="{!users}" var="u" id="u_table">
<apex:column value="{!u.name}"/>
<apex:column value="{!u.Profile__c}"/>
<apex:column headerValue="Signature Name">
<apex:inputField value="{!u.Signature_Name__c}"/>
</apex:column>
<apex:column headerValue="Email">
<apex:inputField value="{!u.Signature_Email__c}"/>
</apex:column>
<apex:column headerValue="Title">
<apex:inputField value="{!u.Signature_Title__c}"/>
</apex:column>
<apex:column headerValue="Phone">
<apex:inputField value="{!u.Signature_Phone__c}"/>
</apex:column>
<apex:column headerValue="Mobile">
<apex:inputField value="{!u.Signature_Mobile__c}"/>
</apex:column>

</apex:pageBlockTable>

</apex:pageBlock>
</apex:form>
</apex:page>
