CakePHP 2.x & JS scripts in AJAX view

Sometimes, after making an AJAX request, we want to use JS scripts in the view of AJAX function.
I was having a trouble with that after switching to 2.0.5 version - a simple AJAX view, including only a text message and a bit of JavaScript code - didn't render and run the script at all.

The solution for this is an evalScripts option in JsHelper.
If you want your AJAX view to display and run <script>'s, simply add this option to your AJAX call.

For example:

<?php
   echo $this->Js->link('update',
      array('controller' => 'controller', 'action' -> 'action'),
      array(
         'update' => '#id_of_element_to_update',
         'evalScripts' => true,
      )
   );
?>
