after append, jquery not found the button

after append, jquery not found the button

hi,
i have append a table with jquery at a button.

now when I click the button , this is not found .
[code]
      $('#tbl').append(
      '<tr>
            <td>
                  <button id="x" class="save" value=" http://www.........">save</button>
            </td>
      </tr>');
[/code]


All buttons that were already in the table , I can respond .
This also works .

[code]
$('save').bind('click', function(){
      alert("test");
});
[/code]


But not the new insertet button....

help??^^
