public function addOne(array &$form, FormStateInterface $form_state) {
  $id_field = $form_state
    ->get('id_count');
  $add_button = $id_field + 1;
  $form_state
    ->set('id_count', $add_button);

  // Since our buildForm() method relies on the value of 'num_names' to
  // generate 'gtag_id' form elements, we have to tell the form to rebuild. If we
  // don't do this, the form builder will not call buildForm().
