I'm sure that I missed something...just that I'm not able to conclude what is it. Please help me out.

Answer 1

This will call showAlert immediately, instead of delaying to when the event fires:

document.addEventListener("deviceready", showAlert('You are the winner!'), false)

Instead do this

document.addEventListener("deviceready", function() {
    showAlert('You are the winner!')
}, false)
