Loaded page form submission

Loaded page form submission

I project I'm working on uses jquerys load to load up pages on my site.

I'm having problems using ajax forms to submit data to a .php page on these loaded pages. They tend to either not work or refresh to the defult page loaded via jquery. 

(document).ready(function(){
 // load index page when the page loads
 $('#ajax-content').html('<p><img src="includes/loaderimage.gif" width="220" height="19" /></p>');
  $('#ajax-topframe').html('<p><img src="includes/loaderimage.gif" width="220" height="19" /></p>');
   $('#ajax-sidebar').html('<p><img src="includes/loaderimage.gif" width="220" height="19" /></p>');
 $("#ajax-content").load("overview.php");
 $("#ajax-topframe").load("index.php?func=topframe");
 $("#ajax-sidebar").load("overview.php?func=siderbar");
 
 $("#articles").click(function(){
  ///////////////////////
 ////// WHAT TO LOAD ON ARTICLE CLICK
 ///////////////////////
 $('#ajax-content').html('<p><img src="includes/loaderimage.gif" width="220" height="19" /></p>');
  $("#ajax-content").load("articles.php");
   $("#ajax-sidebar").load("articles.php?func=sidebar");
 });
 
is the way I'm loading these pages. The form submission is on a page loaded by user click.
