How to use buttonOptions on GridView

Hi

I would like to change the default button name on grid view On YII2

on Yii 1 we have this:

http://www.yiiframework.com/wiki/106/using-cbuttoncolumn-to-customize-buttons-in-cgridview/


array

(

    'class'=>'CButtonColumn',

    'template'=>'{email}{down}{delete}',

    'buttons'=>array

    (

        'email' => array

        (

            'label'=>'Send an e-mail to this user',

            'imageUrl'=>Yii::app()->request->baseUrl.'/images/email.png',

            'url'=>'Yii::app()->createUrl("users/email", array("id"=>$data->id))',

        ),

        'down' => array

        (

            'label'=>'[-]',

            'url'=>'"#"',

            'visible'=>'$data->score > 0',

            'click'=>'function(){alert("Going down!");}',

        ),

    ),

),

I would like something like that for Yii2

For now I would like to change only the label.

Reading the documentation for Yii2 I tried that:




[

    'class' => 'yii\grid\ActionColumn',

    'buttonOptions' => [

        [

            'name' => 'update',

            'additionalOptions' => [

                'label' => 'Super Update',

            ]

        ],

        [

            'name' => 'delete',

            'additionalOptions' => [

                'label' => 'Super Delete',

            ]

        ],

    ],

],



But it does not work.

thanks
