Share This not working in content called via AJAX

Using ajax: Share This not working in content called via AJAX on newest questions tagged ajax – Stack Overflow

I have a page this is pulling in content dynamically with AJAX request and JQuery. Once the content has loaded I use colorbox’s on complete function to Load any script that is needed. One of the things I am trying to load is a ShareThis button and my mark-up is as such:

HTML

<span class="st_sharethis_custom"></span>

Inside colorbox’s onComplete function i have this.

  $.getScript("http://w.sharethis.com/button/buttons.js", function() {});
  var switchTo5x=false;
  stLight.options({publisher: "ur-a4a2b4d1-36da-c1a3-4eee-8eedd1e95feb"});

When I run the lightbox and hover over the ShareThis button I get the following error.

stButtons.messageQueueInstance is null

Any help on this would be greatly appreciated.

Thanks
