Button action is not called on UIViewController added on Paging
===

I'm making one application in which I had added four class on childView 

    [self addChildViewController:homeScreenViewController];
    [self addChildViewController:portFolioViewController];
    [self addChildViewController:watchListViewController];
    [self addChildViewController:marketingViewController];

Than I call the childView on pageControl as paging.
Now on the homeScreenViewController Class I have added a button but the button do not take any action.

Please suggest me.
