WebView change the url after creation (VERY EASY TO READ QUESTION)

I've been having problems left and right with Titanium's webview... Require serious assistance ASAP.

I'm using Alloy. What I'm trying to do is to change the URL of a webview that I've previously created in alloy.js

My alloy.js file first creates a webview:

Alloy.Globals.webview = Titanium.UI.createWebView();
Alloy.Globals.setUserAgent(); //function that just sets the user agent
Alloy.Globals.webview.url = "http://www.google.ca";

Then on index.js, I have a button where when I click it, it creates my controller: "web" and opens it:

var win = $.index;
 
button.addEventListener('click',function(e)
{
    var theTest = Alloy.createController('web').getView();
    theTest.open();
    win.close();
});

On web.js, I add the webview to a view:

$.view_webview.add(Alloy.Globals.webview);

Still on web.js, I have another view where when I click on it, it tries to change the url of this webview:

view_getpoints.addEventListener('click', function(e){
    $.Alloy.Globals.webview.url = "http://www.youtube.com";
});

This didn't work, the webview's url was still at google for some reason. So I tried this:

view_getpoints.addEventListener('click', function(e){
    $.Alloy.Globals.webview.setUrl("http://www.youtube.com");
});

That didn't work either, same result, was still at google.

I then figured I probably need to do it directly to the webview I added rather than to the variable. So I went to output the child of the view I added the webview to just to see if I can get the webview:

view_getpoints.addEventListener('click', function(e){
    Ti.API.info("child: " + $.view_webview.getChildren(0));
}

Sure enough, it outputs: "child: [object WebView]". All great right? No! Despite the fact that I've clearly managed to gain access to the WebView, doing something such as:

view_getpoints.addEventListener('click', function(e){
    $.view_webview.getChildren(0).url = "http://www.youtube.com";
}

Outputs an error saying "url" is undefined. What? This is a WebView. According to the docs: http://docs.appcelerator.com/titanium/3.0/#!/api/Titanium.UI.WebView-property-url

The WebView object has a url field!

Well doing that didn't work as it gave an error. So I tried setUrl() to that child:

$.view_webview.getChildren(0).setUrl("http://www.youtube.com");

Says "setUrl" is undefined. ..H..How?? How could it be undefined when I literally just debugged it and it told me that $.view_webview.getChildren(0) is indeed a WebView Object ??

Help.
