Lightbox Plus and ajaxed load page!?

Hello there!

I have put the code of lightbox plus for pop up the_content of a post…
But
The “next” and “previous” buttons have been ajaxefied with this code:

<script type="text/javascript" charset="utf-8">
jQuery(document).ready(function(){
jQuery('#nav-below a').live('click', function(e){
  e.preventDefault();
  var link = jQuery(this).attr('href');
  jQuery('#theqa').load(link+' #theqa > *');
  });  

  });
</script>

the “next” or “previous” post loads ok but when i click the hyperlink to see the content (in lightbox) of the loaded post it dosen’t pop up!

why?
