Laravel5 AJAX set cookie not working

Could you give me advice please?

I'm saving in COOKIES some data. I create method for this in Laravel, so I call ajax on this method to set cookie but when I try to call next request where I access this cookie value, it is not saved and I can access it in second request... I don't know why... it's quite strange :/

I have this code:

public function setCookie: method in laravel controller to set cookie
var setCookie: function in javascript where I call ajax request to set cookie
var loadEvents: method called after ajax call where I set cookie.


public function setCookie(Request $request) {

    $cookieName = $request->input('cookie_name');
    $cookieVal = $request->input('cookie_val');

    return response()->json(['status' => 'success'])->withCookie(cookie($cookieName, $cookieVal));
}


var setCookie = function (cookieName, cookieVal) {
    $.ajax({
        type: 'POST',
        url: window.setCookieUrl,
        data: {
            cookie_name: cookieName,
            cookie_val: cookieVal,
            _token: getCsrfToken()
        }
    }).done();
};



public function loadEvents(Request $request) {

    $activeCalendarsIds = $request->input('active_calendars_ids');
    if($activeCalendarsIds == null)
        $activeCalendarsIds = Cookie::get('adminActiveCalendars');


    $eventsPage = $this->getPostParam('page');
    $eventsLimit = $this->getPostParam('limit');

    $this->service->setFilter('page', $eventsPage);
    $this->service->setFilter('limit', $eventsLimit);

    $events = $this->service->getCalendarsEvents($activeCalendarsIds);
    $eventList = view('admin/calendar/event_list', ['events' => $events]);

    return response()->json([
        'status' => 'success',
        'data' => '' . $eventList . ''
    ]);

}
