Setting remember on ajax laravel login

Rebuilding my system using laravel 5.4. I do an ajax login that works, but i want to add the remember option to the auth. the documentation says this about setting remember:

if (Auth::attempt(['email' => $email, 'password' => $password], $remember)) {
    // The user is being remembered...
}

But since my logincontroller does not have any visible login function, i am struggling with how to override it with my current logincontroller. in my route i am just calling LoginController@login. and i have no override on the login function being called..

This is my logincontroller:

namespace App\Http\Controllers\Auth;
use App\Http\Controllers\Controller;

use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Lang;
class LoginController extends Controller
{

    use AuthenticatesUsers;
    protected $redirectTo = '/minside';
    public function __construct()
    {
        $this->middleware('guest', ['except' => 'logout']);
    }
    protected function sendLoginResponse(Request $request)
    {
        $request->session()->regenerate();
        $this->clearLoginAttempts($request);
        if ($request->ajax()) {
            error_log($this->guard()->user(),'0');
            return response()->json($this->guard()->user(), 200);
        }
        return $this->authenticated($request, $this->guard()->user())
            ?: redirect()->intended($this->redirectPath());
    }
    protected function sendFailedLoginResponse(Request $request)
    {
        if ($request->ajax()) {
            return response()->json([
                'error' => Lang::get('auth.failed')
            ], 401);
        }
        return redirect()->back()
            ->withInput($request->only($this->username(), 'remember'))
            ->withErrors([
                $this->username() => Lang::get('auth.failed'),
            ]);
    }
}
