[jQuery] Insert content in row

Hi all. I have this very simple content:

<tr>
    <td class="rowContent" id="902_1200_2008">United States</td>
</tr>
<tr>
    <td class="rowContent" id="104_500_2008">Canada</td>
</tr>

When user clicks in any row i'll want to display the details about that row. I'm using this but without success:

$('.rowContent').click(function(){
$.get("getCountryContent.cfm", { u: this.id },
  function(data){
  var $conteudo = trim12( data );
    alert("Data Loaded: " + trim12( data ));
    $( '#' + this.id ).html(trim12( data )).append();
  });
});

This ajax response is an html table...

What's wrong?

Cheers
