In your top image, if it works it works only because you're actively clicking on a specific array element. If you click on, for example, the increment or decrement of the array index the event may fire but you'll get the LAST element that was selected. I think it's kind of happenstance that the first example worked at all. It's certainly not implementing all of the safeguards to make sure it works in every circumstance.
The second image of code you show shows a disabled case of code, but as shown, this code is.... disabled. I presume now you meant to show that it was an alternate version which you also tested? The code as shown does not tell us which code is actually active within the disable structure i.e. int he "Enabled" frame. In the absence of any other information I suppose one would have to assume it's the version shown int he first screenshot....?
