How do I close an iOS game when 'Home' button is pressed?

Hi,

I'm testing a game made with C2 + Phonegap Build on an iPhone.

I've noticed that when you close the game, let pass some time and open it again, the game doesn't reload, just stays at the same screen that you were playing.

I would like it to reload the game so it shows you the menu screen and stuff.

Any ideas?

Thanks!
