How to execute an action before close metro app WinJS

I want to trigger a function before closing my metro app but I don't know where such as

app.onactivated = function (args){
  //all the actions here will be executed on app's activation
}

I want something for deactivation or app's closure, what's the proper way to do this in WinJS

Look at the documentation for both onunload and oncheckpoint. There are differences and you may need one or the other.

I think you'll actually want to tie into the WinJS.Application unload event, which is really just a wrapper for window.onunload, but is the "Windows 8" way to do it:

WinJS.Application.addEventListener("unload", function(e) {
    // do any needed clean up
});

If I am not mistaken, it will be onunload event.

"Occurs when the application is about to be unloaded." - MSDN
