如何更改 Drupal 8 表单元素中的选项名称？

Question

我有 link 'Best' 的公开形式。我希望在用户单击此 link 后，link 标题更改为 'New'

我正在尝试这个，但它不起作用：

function helper_form_views_exposed_form_alter(array &$form, FormStateInterface $form_state, $form_id) {
    if($form['#id']== 'views-exposed-form-pozdravleniya-taxonomy-term-page-1') {
      $form['sort_by']['#title'] = '';
      $form['sort_by']['#options']['created'] = '';
      if ($form['sort_by']['#value'] == 'count') {
        $form['sort_by']['#options']['count'] = 'New';
      }
    }
}

function helper_form_views_exposed_form_alter(array &$form, FormStateInterface $form_state, $form_id) {
    if($form['#id']== 'views-exposed-form-pozdravleniya-taxonomy-term-page-1') {
      $form['sort_by']['#title'] = '';
      $form['sort_by']['#options']['created'] = '';
      if ($form_state->getValue('sort_by') == 'count') {
        $form['sort_by']['#options']['count'] = 'New';
      }
    }
}
