[jQuery] jquery ajax-built page with embedded ajax code issue

[ray]

i've got a page where the body is dynamically generated/regenerated
using ajax with clickable links, using the following snippet to
replace the maintext div w/ the output from the ajax.php script:

   $('.ajax_link').click(function() {
      clicked_link_id = $(this).attr("id");
      $.ajax({
         dataType: "text",
         type: "POST",
         url: "ajax.php",
         data: "a=" + clicked_link_id,
         success: function(msg) {
            $("#maintext").fadeOut("slow", function() {
               document.getElementById('maintext').innerHTML = msg;
               $("#maintext").fadeIn("slow");
            });
         },
         error: function(XMLHttpRequest, textStatus, errorThrown) {
            alert("Error:");
         }
      });
      return false;
   });

sometimes the page info returned from ajax.php (and thus displayed in
the maintext div) itself contains an ajax clickable link.  when this
link is clicked, however, instead of being correctly 'intercepted' by
the ajax snippet above, instead attempting to actually load the link
specified in the href parameter in the browser (which i've set to #,
since i want jquery to handle the link).

any help would be appreciated.
thanks,
