How to display a modal window on a condition?

Question

Yii

Hello,
I have a GridView which has a column with a status, it is editable. How to make a modal window appear when a certain status is selected, for example, I select the "canceled" status, and immediately pop up with options for what reason and the confirm button ...

[
    'class'=>'kartik\grid\EditableColumn',
    'attribute' => 'State',
    'headerOptions' => [
        'style'=>'width: 10%',
    ],
    'editableOptions' => [
        'header'=>'State',
        'inputType'=>\kartik\editable\Editable::INPUT_DROPDOWN_LIST,
        'data'=>Orders::getOrdersStati(),
        'options' => ['class'=>'form-control', 'prompt'=>'Статус...'],
    ],
],

Controller

public function actionIndex()
{
    $searchModel = new Orders();
    $dataProvider = $searchModel->search(Yii::$app->request->queryParams);

    if (isset($_POST['hasEditable']))
    {
        \Yii::$app->response->format = \yii\web\Response::FORMAT_JSON;

        $model = new Orders();
        $stateId = YII::$app->request->post('editableKey');
        $model = Orders::findOne($stateId);

        $post = [];
        $posted = current($_POST['Orders']);
        $post['Orders'] = $posted;

        if ($model->load($post))
        {
            if($model->save())
            {
                if (isset($posted['State']))
                {
                    $output = $model -> State;
                }
                $out = Json::encode(['output'=>$output, 'message'=>'']);
            }
        }
        echo $out;
        die;
    }

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

How to display a modal window on a condition?

This is pure js (jquery), we listen to the event, check what is needed and display it or not. Back (php and yii) has nothing to do with it at all
