iOS - Button click event not workng

I am building an ANE which will start a new View which contains a label and button. I was successful in adding view as bundle and view controller in my .a file.

I am starting my view as a subview. And later when I click button, it should do some stuffs and change the label text. I can display the view using below code but my button click event is not working.

--- Code to start view ---

My ViewController class name is 'VideoViewController' and bundle containing xib name is 'ViewBundle.bundle'

    UIApplication *app = [UIApplication sharedApplication];

    UIViewController *myViewController;

    NSBundle * mainBundle = [NSBundle mainBundle];

    NSString * pathToMyBundle = [mainBundle pathForResource:@"ViewBundle" ofType:@"bundle"];

    NSAssert(pathToMyBundle, @"bundle not found", nil);

    NSBundle *bundle = [NSBundle bundleWithPath:pathToMyBundle];

    myViewController = [[VideoViewController alloc] initWithNibName:nil bundle:bundle];

    [app.keyWindow addSubview:myViewController.view];

--- VideoViewController.h ---

#import <UIKit/UIKit.h>

@Interface VideoViewController : UIViewController

@11377687 (strong, nonatomic) IBOutlet UILabel *textLabel;

@11377687 (strong, nonatomic) IBOutlet UIButton *clickBtn;

- (IBAction)BtnTapped:(id)sender;

- (IBAction)BtnTappped:(UIButton *)sender;

--- VideoViewController.m ---

#import "VideoViewController.h"

@Interface VideoViewController ()

@implementation VideoViewController

#pragma mark - UIViewController

- (void)viewDidLoad {

    [super viewDidLoad];

    [self logMessage:@"From did load"];

    [_clickBtn setUserInteractionEnabled:YES];

    [_clickBtn setTitle:@"Click Here" forState:UIControlStateNormal]; // button text changes here

}

#pragma mark - Public

- (IBAction)BtnTapped:(id)sender {

    [_textLabel setText:@"Btn Tapped"];

}

- (IBAction)BtnTappped:(UIButton *)sender {

    [_textLabel setText:@"Btn Tappped"];

}

#pragma mark - Private

- (void)logMessage:(NSString *)msg {

    NSLog(@"%@", msg);

    [_textLabel setText:msg];

}

I tried to give touch event programmatically, but still button click event doesn't work.

Can anyone please help to sort out this issue?
