How to use ChangeHandler when user doesn't make a change.

How do I use the 
svSC.ChangeHandler =^{
}

if the user doesn't make a change.  I have a situation that user can tap an item and a SVSegmentedControl Pops Up.  Why can't the user tap currently selected Item and have changehandler fire anyway. 

The issue is I want to use blocks not delegate/callback method.  

Thanks for this super cool control Sam!
