Hi Tahir

You need to add a javascript in the editviewdefs.php. Take a look in the modules/Accounts/metadata/editviewdefs.php to understand how to do.
Then you need to add a new attribute in the dropdown field defs:

 'displayParams' => array(
  'javascript' => 'onchange="someFunction();"',
), 
  

Then you need to define this someFunction in the javascript.
