clone and change

clone and change

Is there a problem with trying to fire a .change() on a cloned item? It's not working and I can't figure out why.
  2.   $("#Category").change(function(e) {
  3.     var question_set = this.value;
  4.     var replace_set = $("#question" + question_set);

  6.     // reset box
  7.     $("#question_box").html("");
  8.     $(replace_set).clone().appendTo("#question_box");
  9.     $("#question_box div").attr('id', 'question_set');
  10.     $("#question_box select").attr('id', 'question_one');
  11.     $("#question_set").removeClass('question_hidden');

  13.     e.preventDefault();
  14.   });

  16.   // This is the part that doesn't work. The correct select is there with the correct
  17.   // correct id=question_one but when I change the select box the alert doesn't fire.
  18.   $("#question_one").change(function(e) {
  19.     var selected_question = this.value;
  20.     alert("selected_question: " + selected_question);

  22.     e.preventDefault();
  23.   });

Any help on this one?
