yii2完整日历事件不会拖动

Question

我将事件从数据库传递到视图。使用最新的日历插件。 但是我无法将事件从一天拖到另一天。 这是控制器：

    public function actionAllEventsmod()
{
    $events = Events::find()->all();
    $tasks = [];
    $draggable = "fc-draggable fc-resizable";
    foreach ($events as $eve) {

        $event = new \yii2fullcalendar\models\Event();

        $house = House::getHouseAddress($eve->house_id);
        $details = $house->address_line_1 . " -- " . $house->city . " -- " . $house->comments;

        $event->id = $eve->event_id;
        $event->start = $eve->start;
        $event->end = $eve->end;
        $event->title = $eve->title;
        $event->description = $details;
        $event->className = $draggable;
        $event->editable = true;
        $event->backgroundColor = $eve->background_color;
        $tasks[] = $event;
    }

        return $this->render('all-events', [
        'events' => $tasks,
    ]);

}

视图：

use yii\helpers\Html;
use yii\grid\GridView;
use yii\web\JsExpression;

$JSEventClick = <<<EOF
function(calEvent, jsEvent, view) {
    alert(calEvent.title + ' -- ' + calEvent.description);
}
EOF;

$this->registerJs($JSEventClick);
?>

非常感谢任何帮助。
