Titanium Mobile 3.0 Navigation Controller pass variables between windows - titanium

Question

I am using swanify's Titanium Navigation Controller https://github.com/swanify/Titanium-Navigation-Controller for my app deployed in Android device.
i am trying to pass data that i have selected from a table row here back to the previous page and populate a text field there.
Anyone has any ideas how to do it? i am looking into using events but it doesnt seem to be working for me.
thank you. :)

Here is what I have done in this situation, It makes use of the eventing aspects of JavaScript and Titanium, the general principle is to have your own custom events, fire them on a control, and listen elsewhere.
First lets say we have a file named NextWindow.js that is a CommonJS module encapsulating a window and a tableview, everytime the a row is clicked we capture that event, then fire our own custom event on the window:
function NextWindow() {
var self = Ti.UI.createWindow();
var tableView = Ti.UI.createTableView();
// Other initialization
....
....
tableView.addEventListener('click', function(e) {
// You may have to use e.rowData.title depending on how you created the table view
var rowTitle = e.row.title;
// Now fire a custom event on the window whenever a row is selected
// send the title through as data
self.fireEvent('table_row_selected', {title : rowTitle});
});
return self;
}
module.exports = NextWindow;
When you create a NextWindow to push onto the navigation stack, add a listener for a custom event to it, this is inside of the previous window with the text box:
var NextWindow = require('NextWindow');
var nextWindow = new NextWindow();
nextWindow.addEventListener('table_row_selected', function(e) {
// Do what you want here with the passed back data
var title = e.title;
some_label.text = title;
});
// Open the next window on the NavigationController stack
nav.open(nextWindow);
Now were listening for a custom event attached to the nextWindow. Say you have a TableView in your nextWindow, listen for the TableView click, and fire the custom event:
