cakephp with jquery .load

Question

hi, i've got a problem, i'm using cakephp and im loading into a div a page

   function loadContent(targetDiv, sourceUrl) { 
       $(targetDiv).empty().html('<img src="/gambu/img/ajax-loader.gif" />');
       $(targetDiv).load(sourceUrl);
   }

it work's ok, but in a loaded page i've got autocomplete and thickbox, and that's not working :( when the page is loaded normally without ajax everything is fine. I think that ajax loaded page can't see mine jquery scripts. I've tried livequery but it work's only on something like that:

   $("#check").livequery('click', function(event) { 
       $("#myform").toggleCheckboxes();
       return false; 
   });

but don't know how to use it with autocomplete and thickbox(made by helper in cakephp)
