JavaScript not working after AJAX postback (jQuery Backstretch and Telerik RadAjaxManager)-open source projects srobbin/jquery-backstretch

I am using jQuery Backstretch (http://srobbin.com/jquery-plugins/backstretch/), but after an AJAX update via an RadAjaxManager AjaxRequest (kicked off clientside), it dies.

I have tried re-initializing after the AJAX, but no dice. Other jQuery plugins are still working though (i.e. Countdown for jQuery – http://keith-wood.name/countdown.html).

JS Page Load:

$(document).ready(function () {
  $('#timer').countdown({
    until: new Date(2014, 5 - 1, 1)
  });

  $.backstretch([
    'images/bg1.jpg',
    'images/bg2.jpg',
    'images/bg3.jpg'
     ], {
     fade: 750,
     duration: 4000
  });
});

Javascript called for a button click:

$find("").ajaxRequest();

VB:

Protected Sub RadAjaxManager1_AjaxRequest(sender As Object, e As AjaxRequestEventArgs) Handles RadAjaxManager1.AjaxRequest
    'Do something
End Sub

After the AjaxRequest has run, the Countdown is still running, but the Backstretch images have disappeared!

Help?
