atmbtn backgroundImage change to check_box_on.png meanwhile NSLog printing yesString and again clicking atmbtn there is no change in backgroundImage same check_box_on.png meanwhile NSLog Printing same yesString only.. again and again clinking the atmbutton same only happening..

- (IBAction)atmAction:(id)sender{  
    if( [atmbtn backgroundImageForState:UIControlStateNormal] ==
        [UIImage imageNamed:@"check_box_on.png"] ) {
       [atmbtn setImage:[UIImage imageNamed:@"check_box_off.png"] 
               forState:UIControlStateNormal]; 

        noString = @"No"; 
        NSLog(@"atm=%@",noString);
    } else if( [atmbtn backgroundImageForState:UIControlStateNormal] ==
                [UIImage imageNamed:@"check_box_off.png"]) {

        [atmbtn setImage:[UIImage imageNamed:@"check_box_on.png"]
