SharePoint 2013 - AJAX - Post Back - Removes Page Title

I am using Update Panel in a custom webpart and whenever it posts back it removes the page title.

Anyone knows how to fix it in the HTML master page??

I used to face this issue in SharePoint 2010 and fix it using the code below but I have no idea how to fix it in SharePoint 2013

Change this in Master page from:-

<titleid=”onetidTitle”><asp:ContentPlaceHolderID=”PlaceHolderPageTitle”runat=”server”/></title>

<titleid=”onetidTitle”><asp:ContentPlaceHolderID=”PlaceHolderPageTitle”runat=”server”/></title>
