Same click function for numerous links

Same click function for numerous links

I have links on my page that get their attributes via PHP from MySQL. 

<a href='#' class='link_click' id='<?php echo $myid; ?>' >My_Link_1</a><br>

<a href='#' class='link_click' id='<?php echo $myid; ?>' >My_Link_2</a><br>

<div id='my_container'> </div>

The '$myid' php variable will be different every time.  I then pass the id (via .load() POST) to another PHP script and load that page in my_container.  Here is the jquery syntax:

$(document).ready(function(){
  $('.link_click').click(function(){
      $("#my_container").load("classes/class.file.php", {proj: $(this).attr('id')} );
   
      return false;
  });
});

When I initial click on the first link, this works perfectly!  However, I can not click on any links after that.   The status bar just says 'done' and firebug doesn't report anything.  How can I reuse my click function to load reload the page in the same container when a user hits the second link after the first? 

Thank You
