Changing CrudTrait actions

namespace app\controllers;

use app\models\News;
use strongsquirrel\crud\CrudTrait;

class NewsController extends Controller
{
    use CrudTrait {
        actions as traitActions;
    }

    public $modelClass = News::class;

    public function actions()
    {
        $actions = $this->traitActions();

        unset($actions['view']);
        unset($actions['update']);
        unset($actions['delete']);
        unset($actions['search']);

        $actions['create']['afterSave'] = function () {
            return $this->redirect('index');
        };

        return $actions;
    }
}
