Use of Laravel 5.2 roles Package

In laravel5.2 with roles this package, want to get the current login user role, get an empty collection, why?
Model:

class User extends Model implements AuthenticatableContract, CanResetPasswordContract, HasRoleAndPermissionContract{    use Authenticatable, CanResetPassword, HasRoleAndPermission;    protected $fillable = [        'name', 'email', 'password',    ];    protected $hidden = [        'password', 'remember_token',    ];}

Controller:

public function index()    {        $user = \Auth::user();        $name=$user->name;        $role = $user->getRoles();      //  return view('index', compact('name','role'));        dd($role);    }

DD () Results:

Collection {#370 ▼  #items: []}
