Alert dialog not working in Lua

Question

I am using Lua with Gideros and having alert box to show up when back button is pressed.According to Gideros documentation, when first button is pressed, it returns index 1 but it does not really seem to work this way.I tested the app on my android phone.I realized the oncomplete function is not getting called at all, since I tried using a print statement and even it was not executed, so any idea why is is not getting called?

local function onKeyDown(event)
if event.keyCode == KeyCode.BACK then

        local alertDialog = AlertDialog.new("Confirmation", "Are you sure you want to exit?", "Cancel", "Yes")
        alertDialog:show()
        stage:addEventListener(Event.COMPLETE, oncomplete)
        end
end

function oncomplete(e)
if e.buttonIndex == 1 then 
stage:addEventListener(Event.APPLICATION_SUSPEND, suspend)
application: exit()
end

end

function suspend()
application: exit()
end

-- key events are dispatched to all Sprite instances on the scene tree (similar to mouse and touch events)
stage:addEventListener(Event.KEY_DOWN, onKeyDown)

How does it work? What are you getting there instead? Are you getting anything there? If not what is happening? — Etan Reisner, May 07 '14 at 16:57
@EtanReisner: Actually, nothing happens! Alert dialog shows up and when I click on it, no event is dispatching.nothing happens! — systemdebt, May 07 '14 at 18:22
Does the `COMPLETE` event fire on the stage or does it fire on the `alertDialog`? — Etan Reisner, May 07 '14 at 18:53
Then should you be adding the listener on `stage` or on `alertDialog`? — Etan Reisner, May 07 '14 at 19:07
@EtanReisner : Oh, yes :) Thanks a ton :) It worked! Added listener to alertDialog :D — systemdebt, May 07 '14 at 20:13

As per the conversation the issue was that the event listener for the alert box close event was being attached to the stage instead of the alert dialog.

stage:addEventListener(Event.COMPLETE, oncomplete)

instead of

alertDialog:addEventListener(Event.COMPLETE, oncomplete)
