Back button method not fires in objective-c

Question

I customized back button. and then I wanted the backButtonTapped be called when tapping on back button. but it is not called.

 UIImage *backBtn = [UIImage imageNamed:@"back-image"];
 backBtn = [backBtn imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
 self.navigationController.navigationBar.backIndicatorImage = backBtn;
 self.navigationController.navigationBar.backIndicatorTransitionMaskImage = backBtn;

 self.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"" style:self.navigationItem.backBarButtonItem.style target:self action:@selector(backButtonTapped)];


- (void) backButtonTapped {
    [self.navigationController popViewControllerAnimated:YES];
}
