title: Yii2 Pjax GridView action buttons issue
body: <p>I am trying to make an Ajax GridView using Pjax. Everything is working fine except the view, update and delete buttons are not AJAX. The code is:</p>
  
  <pre><code>&lt;?php yii\widgets\Pjax::begin(['id' =&gt; 'demo']); ?&gt;
  &lt;?= GridView::widget([
      'dataProvider' =&gt; $dataProvider,
      'columns' =&gt; [
          ['class' =&gt; 'yii\grid\SerialColumn'],
  
          'id',
          'name',
  
  
          ['class' =&gt; 'yii\grid\ActionColumn'],
      ],
  
  ]); ?&gt;
  &lt;?php yii\widgets\Pjax::end(); ?&gt;
  </code></pre>
  
  <p>The problem is that the links for delete, view and update have the attribute data-pjax=0 which disables AJAX functionality. I cant find out how to set it too data-pjax=1.  </p>
