Processing data from a user source in jQuery-ui autocomplete

Question

I am trying to use jquery-ui to autocomplete in a search box. Since the search depends on the value of another form field, I use the callback for the source. I see that the request has been sent correctly. My remote script returns a simple array of strings, and at this point I cannot get it to work. A drop-down list is never built. Can someone tell me why? Here is the code:

    $(document).ready(function(){
    $("#species").autocomplete({
      source: function( request, response ) {
        $.ajax({
          url: "/includes/species-ajax.cfm",
          dataType: "jsonp",
          data: {
            term: request.term,
            searchBy : function() { 
              var sb = $("#searchBy_hidden").val();
              return (sb ? sb : 'common_name'); }
          },
          success: function( data ) {
            response( $.map( data, function( item ) {
              return {
                label: item.name,
                value: item.name
              }
            }));
          }
         });
    }});
  });

<input type="hidden" name="searchBy_hidden" id="searchBy_hidden" value="common_name" />
Enter the name of a species: <input type="textbox" size="30" id="species" />

Thank,

Try changing dataTypeto 'json', not'jsonp'
