Widget EventListener

I'm using the com.appcelerator.login widget. I'm creating it in the index.js controller. I would like to be able to access the widget's event listeners so I can tell when the window (which widget creates) closes. Scenario: App opens, if user not logged in the opens the login widget, after login the widget (window) closes, app then opens navigation controller.

Problem: "undefined [loginWindow] is not a function...."

index.js

//index. js
 
$.loginWindow = Alloy.createWidget('com.appcelerator.login');
 
$.loginWindow.addEventListener('open', function() {
    if (OS_ANDROID) {
        $.loginWindow.activity.actionBar.hide();
    }else{
        setTimeout(function(){
            alert('works here too...');
        },5000);
 
    }
});
