[TIMOB-16318] TextField: Events - 'change' event does not get fired if you change TextField.value from a Button 'click' callback

*Details:* 'change' event does not get fired if you change TextField.value from a Button 'click' callback. *This is not a regression as this occurs with SDK 3.2.0.GA.* *Steps to reproduce:* 1. Install the following app.js to an iOS device

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

var textField = Ti.UI.createTextField({
	top : 10,
	value : 'TestChangeEvent'
});

textField.addEventListener('change', function(e) {
	Ti.API.info("Change Event Fired: " + e.value);
});

win.add(textField);

var button = Ti.UI.createButton({
	top : 150,
	title : "change textfield.value"
});

button.addEventListener("click", function() {
	textField.value = "changed";
});

win.add(button);
win.open();

2. While having the Xcode console up, press on the "change textfield.value" button *Actual:* "Change Event Fired" does not appear in the Xcode console. *Expected:* "Change Event Fired" should appear in the Xcode console whether you change the textField.value by typing something different or from the button.
