yii2 GridView列表中删除数据回到第一页 [ 2.0 版本 ]

[
    'class' => 'kartik\grid\ActionColumn',
    'deleteOptions' => ['label' => '<i class="glyphicon glyphicon-remove"></i>'],
    'template' => '{view}{update}{delete} ',//只需要展示删除和更新
    'buttons' => [
        
        'delete' => function ($url, $model) {
            return Html::a('  <i class="glyphicon glyphicon-remove"></i>  ',
                Yii::$app->urlManager->createUrl(['delete','id' => $model->id]),
                [
                    'class'=>'w1-action-del a_delete',
                    'title' => Yii::t('yii', '删除'),
                    'id'=>'a_delete',
                    'data-pjax'=>'true',
                ]
            );
        },
    ],
],

不是设置了 'data-pjax'=>'true',这个就指定了ajax吗？还是要自己重新写js绑定事件还有页面的html？？？
