How to pass Variable to Views in Laravel Controller

I have a controller in Laravel 5.0 like this-

    <?php

    namespace App\Http\Controllers;

    use Illuminate\Http\Request;
    use App\Http\Requests;
    use App\Http\Controllers\Controller;

    class CustomersController extends CustomerLayoutController
    {
        public function getDashboard()
        {
            return $this->view('layouts.customer.dashboard', []);
        }

        public function getTest()
        {
            return $this->view('layouts.admin.webinar', ['qustions' => DB::table('qustions')->get()]);
        }
    }

So, I want to pass DB::table('qustions')->get() as a parameter to my views, but I m getting error.

What I am doing wrong?
