Visualforce Component not rendering Page block to show duplicate records on Save

We have a custom new contact visualforce page which uses visualforce component.
Recently we planned on implmenting Duplicate Matching rules to show Duplicate records(if any) up on saving a new record. 

we used the following link provided by Salesforce to write our custom visualforce logic to show duplicate matching records.
https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_class_Datacloud_DuplicateResult.htm

We wrote the code in the custom component and component controller. The problem is that upon save it is not rendering the duplicateresult table(This table shows the duplicate records if any). 

Contact Visaulforce Page
<apex:page standardController="Contact" extensions="NewContactPageWithAddressController">
    <apex:sectionHeader title="New Contact"/>
    Contacts not associated with accounts are private and cannot be viewed by other users or included in reports.
    
    <c:ContactForms contact="{!contact}" redirect="true"/>
</apex:page>
Contact Controller
public with sharing class NewContactPageWithAddressController {
    public Contact contact{get;set;}
    public ApexPages.StandardController standardController {get;set;}
    
    public NewContactPageWithAddressController(ApexPages.StandardController controller) {
        standardController = controller;
        this.contact = new contact();
        this.contact.accountId = ApexPages.currentPage().getParameters().get('accid');
    }   
}

Visualforce Component: Contactform 
 
<apex:component controller="ContactFormsCont" allowDML="true">

        return save() == null ? null : pg;
    }
}

Please see the highlighted code which needs to rerender the page block in Visualforce component id = DupRecords.

Thanks for your help.

Generally speaking the element that you are re-rendering needs to be above the elements that are being re-rendered, in terms of the DOM.  In other words, try applying the id="DupRecords" attribute the apex:form above instead.  Also, the rendered attribute behaves oddly sometimes when using straight up boolean values.  So try changing 
rendered="{!hasDupResult}"

To
 
rendered="{!IF(hasDupResult,true,false)}"


Putting them together you get something like:
 
<apex:component controller="ContactFormsCont" allowDML="true">

	<apex:attribute name="onSave" description="Javascript to be executed when record successfully saves" type="String" />

If updating the VF page like above doesn't work, then it could be something with your Apex method not returning the expected values correctly.  In that case, you'll want to enable debug logs for the running user, and then try saving the records in your VF page, before investigating the debug log.

Yes, the change worked perfectly. 
Thanks you very much for your help.
