[jQuery] Replacing html in ajax success callback?

[s.ross]

Hello--
I have what seems a simple problem, but it's somehow not working out.  
Here's the problem:

   $(".pastebinLink a").livequery(function(){
     $(this).bind('click', function(el){
       $.ajax({
         url:  this.href,
         type: 'post',
         success: function(results, status) {
           $(this).replaceWith(results);
         }
         });
       return false;
     });
   });

The (X)HTML looks like this:

<td class="pastebinLink">
  <a class="modal" href="/pastebin_items/14266/edit">
    <img class="viewButton" src="/images/spacer.gif?1210022683"  
alt="Spacer"/>
  </a>
</td>

And the stuff returned from the Ajax post looks like:

<a href="/pastebin_items/14275/edit" class="modal"><img alt="Spacer"  
class="viewButton" src="/images/spacer.gif?1210022683" /></a>

What I expect is that on success everything inside the <td> should be  
replaced with the new stuff from the server. What am I missing?

Thanks (he says missing something obvious :)
