jQuery Forms Plugin: append response text?

jQuery Forms Plugin: append response text?

I've been banging my head over this. Is it possible to append the responseText as an li element rather than replace it?

I have something like this that doesn't work: 

  1. $(document.ready(function () {
  2.       var options = {
  3.             target: "#ul_element",
  4.             beforeSubmit: validate,
  5.             success: function () { $("#ul_element").append(responseText); }

Thanks!
