I have created a VF page that select multiple records from child (Contingency__c) and add them to parent (Billing_Change_Form__c) related list. Everything work fine other than one issue. Upon selecting a checkbox, the list renders itself with the same records. Here are the screen shots: Without Clicking: enter image description here

When I select a record it show this: enter image description here

They are the same records but added 2 more times.

My visualforce code:

<apex:page showHeader="Fasle" standardController="Billing_Change_Form__c" extensions="test2">
    <apex:form >
    <apex:PageBlock id="counter">

                    <apex:pageBlockButtons>
                      <apex:commandButton value="Save" action="{!mySave}" onComplete="window.top.close();"/>   
                      <apex:commandButton value="Cancel" onclick="window.top.close();" immediate="true" action="{!closePopup}"/>  
                </apex:pageBlockButtons>

            <apex:pageBlockTable value="{!show}" var="e" title="show">

            <apex:column >
                <apex:inputCheckbox value="{!e.check}"/>
    <apex:actionSupport event="onclick" action="{!inIt}"/>
                </apex:column>

                <apex:column value="{!e.con.Name}"/>
                <apex:column value="{!e.con.discovery_amount__c}"/>
                <apex:column value="{!e.con.billing_begins_date__c}"/>
                <apex:column value="{!e.con.report_description__c}"/>
                <apex:column value="{!e.con.contingency__c}"/>
            </apex:pageBlockTable>



        </apex:PageBlock>

You need to re-initialize your list

public List < conCase > getShow() {
    caseList = new list <conCase> (); // this is the fix
        for (Contingency__c coObj: [Select id, name, billing_type__c, report_description__c, discovery_amount__c,
                billing_begins_date__c, contingency__c, VENDOR_INVOICE__r.Account_del__r.Id from Contingency__c
                where(VENDOR_INVOICE__r.Account_del__r.Id =: accID[0].Account__c)
            ]) {
            caseList.add(new conCase(coObj, allBool));
        }
    return caseList;
}
