Event listener does not listen after having used $.post

Event listener does not listen after having used $.post

Hi,

I've got an Event Listener

$(".SFV").click(function(event) ...

And I've got an submit button 

< ... type="submit" class="SFV">

When this button is displayed in a normal html-script, the event listener works. When I insert this button into the same script with the help of

  1. $.post("do/setFieldVal_Input.php", {table:table, whereFieldName:whereFieldName, whereVal:whereVal, setFieldName:setFieldName, idHtml:idHtml}, function(data)
  2.    {
  3.       //document.getElementById('test').innerHTML=data;
  4.       document.getElementById(idHtml).innerHTML=data;
  5.     });    

then the listener does not work anymore.

Why is that?

Thx
