Titanium up caret and menu item on actioinbar not working - titanium-mobile

Question

I have the following code for a window. I'm trying to implement the up caret so a user can go to the previous window by tapping the title.
The up caret appears, but when i tap it, nothing happens, it only glows.
The menu item i added doesn't show either.
Is there something i'm not doing right?
function ConfirmOrder(_args) {
var actionBar;
var self = Ti.UI.createWindow({
title : "Confirm Order",
backgroundColor :'transparent',
orientation : 'vertical'
});
self.addEventListener("open", function() {
actionBar = self.activity.actionBar;
if (actionBar) {
actionBar.title = "Confirm Order";
actionBar.displayHomeAsUp = true; // shows up caret
actionBar.onHomeIconItemSelected = function() {
self.close();
};
} else {
alert('actionbar not accessible');
}
self.activity.onCreateOptionsMenu = function(e) {
var menu = e.menu;
var menuItem1 = menu.add({
title : L('settings'),
icon : "images/Setting.png",
showAsAction : Ti.Android.SHOW_AS_ACTION_IF_ROOM
});
menuItem1.addEventListener("click", function(e) {
alert("Settings Options Menu");
});
};
});
var imgView = Ti.UI.createImageView({
top : '3%',
image : Titanium.App.Properties.getString('image'),
height : '30%',
width : '60%'
});
var bottom = Titanium.UI.createView({
top : '37%',
height : '55%',
orientation : 'vertical',
touchEnabled : false,
backgroundImage : '/images/bg2.jpg',
});
var buttonsView = Titanium.UI.createView({
bottom : '0%',
height : '10%',
orientation : 'horizontal',
touchEnabled : false,
});
var confirmButton = Ti.UI.createButton({
right : '5%',
bottom : '10%',
width : '40%',
height : '70%',
color : 'white',
font : {fontSize:20, fontWeight:'bold', fontColor:'white', fontFamily:'Helvetica Neue'},
title : 'Confirm'
});
confirmButton.addEventListener('click', function(evt) {
// blah blah blah
});
var cancelButton = Ti.UI.createButton({
left : '5%',
bottom : '10%',
width : '40%',
height : '70%',
color : 'white',
font : {fontSize:20, fontWeight:'bold', fontColor:'white', fontFamily:'Helvetica Neue'},
title : 'Cancel'
});
cancelButton.addEventListener('click', function(evt) {
// blah blah blah
});
// add buttons to buttons container
buttonsView.add(confirmButton);
buttonsView.add(cancelButton);
// add parent containers to windows
self.add(imgView);
self.add(bottom);
self.add(buttonsView);
return self;
};
module.exports = ConfirmOrder;
Thanks all

I can't quite put my finger on it because it looks very similar to how i do it. However the only thing that i have different is that I have another check to ensure that you can get the activity, could it fall into this trap?
if (! self.getActivity()) {
Ti.API.error("Can't access action bar on a lightweight window.");
} else {
actionBar = self.activity.actionBar;
if (actionBar) {
actionBar.title = "Confirm Order";
actionBar.displayHomeAsUp = true; // shows up caret
actionBar.onHomeIconItemSelected = function() {
self.close();
};
} else {
alert('actionbar not accessible');
}
}
If the other options aren't working either I would remove them to see if they are somehow causing the up caret to error.
Hope that helps
