jQuery Tools Tooltip - Change Title

Got a problem with the jquery plugin Tools tooltip (http://flowplayer.org/tools/tooltip/index.html) I need to change the title of the element..

   reloadTooltip();
   $("#example").attr('title', obj.text);
   reloadTooltip();

   function reloadTooltip(){
       $("[title]").tooltip({ position: "bottom right", opacity: 1 });
   }

Html Part:

   <span title="text" id="example"></span>

With my solution i got finally 2 titles, one above the other. The unstyled (ignored js), is the new one. The Tools tooltip title has not changed yet.

thank you
