Why is my external screen not responding?

I'm making an iOS app that interacts with an external monitor and the problem is that I can't find the reason why the "actions" don't have any effect.

Example: Trying to launch function "getData" (ExternalViewController) from BettingEntranceViewController.

Using separate storyboards for iPad and External monitor.

ViewController.h

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController

@end

ViewController.m

#import "ViewController.h"
#import "ExternalViewController.h"

@interface ViewController ()

@property (strong, nonatomic) IBOutlet UITextView *loger;
@property (strong, nonatomic) UIScreen *extScreen;
@property (strong, nonatomic) UIWindow *extWindow;

@end

@implementation ViewController

- (void)logMessage:(NSString*)message
{
    self.loger.text = [self.loger.text stringByAppendingString:message];
    [self.loger scrollRangeToVisible:NSMakeRange([self.loger.text length], 0)];
}

- (void)screenDidSomething:(NSNotification *)notification
{
    NSArray *screens;

    screens = [UIScreen screens];
    NSUInteger screenCount = [screens count];

    if (screenCount > 1) {
        self.extScreen = screens[1];
        [self logMessage:@"Wuhu ext is!"];
    } else {
        self.extScreen = nil;
        self.extWindow = nil;
    }

    self.extWindow = [[UIWindow alloc] initWithFrame:self.extScreen.bounds];
    self.extWindow.screen = self.extScreen;

    [self logMessage:[NSString stringWithFormat:@"External screen resolution: %f x %f \n", self.extScreen.bounds.size.width, self.extScreen.bounds.size.height]];

    UIStoryboard *externalStory = [UIStoryboard storyboardWithName:@"External" bundle:nil];
    ExternalViewController *externalTroller = [externalStory instantiateInitialViewController];
    self.extWindow.rootViewController = externalTroller;

    self.extWindow.hidden = NO;
}

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];

    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(screenDidSomething:)
                                                 name:UIScreenDidConnectNotification
                                               object:nil];

    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(screenDidSomething:)
                                                 name:UIScreenDidDisconnectNotification
                                               object:nil];
}

- (void)viewDidDisappear:(BOOL)animated
{
    [[NSNotificationCenter defaultCenter] removeObserver:self
                                                    name:UIScreenDidConnectNotification
                                                  object:nil];

    [[NSNotificationCenter defaultCenter] removeObserver:self

                                                  object:nil];
}
