Laravel registration email approve

Okay so i got script based on laravel framework:

    public function confirm($activationCode)
{
    if( ! $activationCode)
    {
        throw new InvalidActivationCodeException;
    }

    $user = User::whereActivationCode($activationCode)->first();

    if ( ! $user)
    {
        throw new InvalidActivationCodeException;
    }

    $user->activated = 1;
    $user->activation_code = null;
    $user->save();

    return Redirect::route('login_path');
}

}

He's checking database cell activation_code. My route.php looks like that:

ModuleRoute::controller('auth/registration/approve/{activationCode}', 'RegistrationController@confirm');

But then i go to the link: http://default.com/auth/registration/approve/some activation id/ i got error: Controller method not found.

What's the problem?
