Titanium Mobile: Using JS-only event dispatcher

dispatcher.js

var dispatcher = require('dispatcher');

function onLogOutButtonClick(e) {
    dispatcher.trigger('logout');
}

receiver.js

var dispatcher = require('dispatcher');

dispatcher.on('logout', function onLogOut(e) {

    // so the dispatcher doesn't keep us from GC
    dispatcher.off('logOut', onLogOut);
});
