点击gridview Yii2中的按钮打开模态

Question

我需要在网格中打开一个模态按钮，但是不能正常工作

这是专栏：

['class' => 'yii\grid\ActionColumn',
            'template' => '{getRespostaPossivel}',
            'buttons' => [
            'getRespostaPossivel' => function ($url, $model) {
                    if($model->classeResposta->indr_resposta_possivel){
                        return Html::buttonInput('Respostas Possíveis',['class'=>'btn btn-primary btn-xs','id' => 'modal-open','onclick' => 
                            "$('#modal').modal('show');
                            $.ajax({
                                url : 'getFormRespostaPossivel',
                                data : {'id' : $model->id},
                                success  : function(data) {
                                    $('.modal-body').html(data);
                                }
                            });
                        "]);
                    }
                },
            ],
        ],

和行动：

public function actionGetFormRespostaPossivel($id)
    {
        $searchModel = new RespostaPossivelUsuarioSearch();
        $searchModel->tblcaus_id = $id;
        $dataProvider = $searchModel->search(Yii::$app->request->queryParams);

        return $this->render('_form', [
            'searchModel' => $searchModel,
            'dataProvider' => $dataProvider
        ],true,true);
    }

有人可以帮我解决这个问题吗？
