jquery and an if statement Drupal 7. I have a radio button set. When one of the items is selected I would like it to set the node add title to some string. This is as far as I got, but I get the error: "TypeError: '[object Object]' is not a function (evaluating '$("#edit-field-i-need-help-with-und-printer-ink")')"

(function ($) {
      Drupal.behaviors.cgps_helpdesk_misc = {
        attach: function (context, settings) {
          $("#edit-field-i-need-help-with-und-printer-ink").change(function ($) {
              if ($("#edit-field-i-need-help-with-und-printer-ink").attr("checked")) {
                alert('Handler for .change() called.');
                $('#edit-title').val($('#edit-title').val() + 'bla bla bla');
              }
          });
        }
      };
    }(jQuery));
What MPD is saying is change this line:

$("#edit-field-i-need-help-with-und-printer-ink").change(function ($) {


to this:

$("#edit-field-i-need-help-with-und-printer-ink").change(function () {


You have declared two functions as $ and that may be killing the script.
