i have written this code to apply 'jQuery Tooltip plugin' to ajax loaded elements.

i mean the row i want to show tooltip on its mouseover is loaded into page by ajax. here's the code:

$("[id^=pane]").delegate("[id^=comm]","mouseover",function() {

   $(this).tooltip({

      // each trashcan image works as a trigger
      tip: "#tooltip",
      // custom positioning
      position: "center right",
      // move tooltip a little bit to the right
      offset: [0, 15],
      // there is no delay when the mouse is moved away from the trigger
      delay: 0
  }).dynamic({ bottom: { direction: "down", bounce: true } });

});

the tooltip is shown when mouseover but firebug report this error:

"$(this).tooltip({tip: "#tooltip", position: "center right", offset: [0, 15], delay: 0}).dynamic is not a function"

is it because of using $(this) ???
