I think you may be confusing what needs to happen here. The setupItem method should only be called in response to the onSetupItem event that is thrown by the list when you .setCount() on it or .build() it.

So, the handler for ontap of your button should set the contents of the array, then either change the count on the list (with setCount()) or call .build() on it directly.
