How to reload the custom javascript file after Drupal makes ajax call?

Hi,

How one can reload the custom javascipt file after ajax call is completed.

In my case I have a custom javacript file to manipulate the views data and
filters. It works perfectly first time.

But once the user sets filter and hit Apply i:e after ajax call the javascript
loose its importance. Its their but not registering any event.

I read some articles on Drupal.org but didn't get some solid solution.

Note - Its not a module .js file but a custom stand alone .js file under the theme folder.

Thanks in Advance
