Problems twig GridView.widget

Hello community , I am currently studying the various changes Yii2 but I have the following problem , since I want to generate a GridView with twig the problem is I want to make my template personalized way, which I did not throw any type of error except that my template it is not visible in the view. I’m using this code.

{{ use(‘yii\grid\GridView’) }}

{{ use(‘yii/bootstrap’) }}

{{ use (‘yii\helpers\Html’) }}

{{ use (‘yii\grid\ActionColumn’) }}

{{ use (‘yii\grid\SerialColumn’) }}

{{ GridView.widget({

'dataProvider' : dataProvider,


'filterModel' : searchModel,


'columns':[


	{'class':'yii\\grid\\SerialColumn'},


	'id_leccion',


	'nombre_leccion',


	'descripcion',


	{


		'header' : 'Acciones',


		'class':'yii\\grid\\ActionColumn',


		'template' : '{vista}',


		'buttons' : [


			{


				'vista':[


					{


					'label':'asd',


						'icon':'glyphicon glyphicon-user',


					},


				],


			},





		],


	},








],

}) | raw }}

If someone happened the same error or recommendation for the custom template so would be great to be displayed . I’ve gotten as generate but as the framework of predefined not give way and the project that I am am currently using TWIG as template engine . No more do I say goodbye refencia waiting for your reply soon
