Add this to your script (if using .Net 3.5 or less). It will notify the Microsoft Ajax Library that the JavaScript file has been loaded.

if (typeof (Sys) != 'undefined')
{
    Sys.Application.notifyScriptLoaded();
}

Note: This is obsolete in .Net 4

You need to run your code (best as a named function) as part of the endRequest event as well, for example you can have a named function like this:

function doStuff() {
  //do whatever here
}

Then run that function where needed:

//run on DOM ready
$(doStuff);
//also run it when UpadtePanels finish/reload
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(doStuff);
