I don't follow your stuff, but I had a look at this one and a couple 
things stood out to me:

* You're casting a `MyButton` to `MyButton*` in two places. That doesn't 
make sense. Cast to `void*` if you want to see the class reference as a 
pointer.

* The text says "for() loop", but you're actually using `foreach` in the 
code.

* If `newButton` "lasts the lifetime of the for() loop", then better 
declare it in the loop, not as a field of the class.

* `return(index);` - Lose the parentheses. `return` is not a function.

* You're converting `lastButtonID` from int to string and back to int. 
That's some pointless back-and-forth.
