[TIMOB-15252] Android: Cannot reference proxy methods

On iOS you can do:

var w = Ti.UI.createWindow({
    backgroundColor: 'white'
});

w.open();

var setter = w.setBackgroundColor;

setter('green');

But on Android you'll get:

08-19 15:23:55.515: E/V8Exception(23104): Exception occurred at app.js:7: Uncaught TypeError: Illegal invocation

This is unfortunate, because this means you cannot link an Alloy widget's exported methods through to one of it's view elements.

I dont think you can get a reference to a method like that on Android. It is because of the native implementation
