Close UIViewController on button click

I am opening a viewcontroller(with a navigation bar and a bar button item for closing the view controller).This is view controller is for displaying information to the user when he clicks on a 'Help' button.The navigation is like this: ViewController1 -> "Help" button -> Viewcontroller2. The Viewcontroller2 has a "Close" button which dismisses this ViewController. I have the Close button with an IBAction hooked to the File's owner.But the break-point is not hit when I click the 'close' button. The code is:

DetailViewController.m(viewcontroller1):

-(void) showHelp:(id)sender
{
    HelpViewController *helpWindow = [[HelpViewController alloc]initWithNibName:@"HelpViewController" bundle:[NSBundle mainBundle]];
    helpWindow.modalPresentationStyle = UIModalPresentationFormSheet;
    [self presentModalViewController:helpWindow animated:YES];
}

HelpViewController.m(viewcontroller2):

#import "HelpViewController.h"

@interface HelpViewController ()

@end

@implementation HelpViewController

@synthesize scrollView;


- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
}

- (void)viewDidUnload
{
    [super viewDidUnload];
    // Release any retained subviews of the main view.
    // e.g. self.myOutlet = nil;
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

- (IBAction)closeAction:(id)sender {
    [self dismissModalViewControllerAnimated:YES];

}

@end

I tried putting a breakpoint at "closeAction" but it isn't hit. I am new to iOS development.I am missing something very obvious here.Any help is appreciated!

Click your Close button and select connection inspector tab in the right side tools. Check your button is connected with closeAction: this method in touchUpInside mode.

If not, then connect your UIButton outlet to this method -(IBAction)closeAction:(id)sender; and then try.

UPDATE: if your button is UIBarButtonItem, then there will be an option as "New referencing outlet". drag from that and connect with your method.
