function ajax_example_submit_driven_callback($form, $form_state) {
  // In most cases, it is recommended that you put this logic in form generation
  // rather than the callback. Submit driven forms are an exception, because
  // you may not want to return the form at all.

  $element['#markup'] = "Clicked submit ({$form_state['values']['op']}): " . date('c');
  return $element;
