Fire an event after Featured Image selection

I figure it out. This may be a bad solution but atleast it works

 $('.inside').bind('DOMNodeInserted DOMNodeDeleted', function(event) 
 { //WRITE WHAT YOU NEED TO DO}

Inside a file abhiScript.js (could be any filename 🙂 )

and

wp_enqueue_script( 'SimpleScript', get_template_directory_uri() . '/assets/js/abiScript.js',array('jquery'));

in function.php
