cordova - PhoneGap iOS CDVViewController not responding to touches -

so have created own uiviewcontroller , placed following lines inside viewdidload. view draws fine unresponsive touch. might cause problem?

- (void)viewdidload {     [super viewdidload];      cdvviewcontroller* viewcontroller = [cdvviewcontroller new];     viewcontroller.view.frame = self.view.bounds;     [self.view addsubview:viewcontroller.view];      [self addchildviewcontroller:viewcontroller]; } 

i'm using phonegap 2.8/2.9 , ios 6.1
