CommonJS module project - undefined is not a function when called multiple times.

Hi guys.

I'm putting together a JavaScript module and mostly things work as expected. I have a simple test, which features two views. On a button click, the first view creates a new instance of the second view and adds it as a child. Both views use my custom JS module. But after 2 or 3 times of creating the child view, my module's function's aren't accessible; I get 'undefined' is not a function. Here are some code samples:

[Slideshow.js - this is where the code fails]

function slideshow(container) {
    var iron = require("com.jasonsultana.IronForge");
    Ti.API.debug("IronForge: " + JSON.stringify(iron));
 
    iron.hello();
 
    return Ti.UI.createView({
        top: 0, left: 0, height: 0, width: 0
    });
}

[FirstView.js]

function FirstView() {
    var iron = require("com.jasonsultana.IronForge");
    var slideshow = require("ui/common/slideshow");
 
    var v = Ti.UI.createView({
        top: 0, height: '100%', left: 0, width: '100%', backgroundColor: 'white'    
    });
    v.addEventListener('click', function(e){
        this.add(new slideshow(this));
    });
 
    return v;
}

[Slideshow.js]

var IronForge = {
    hello: function() {
        Ti.API.debug("Hello World");
    }
}; 
 
module.exports = IronForge;

For the record, I've tried defining this as IronForge.hello = function(){}, but it produces the same result. I didn't want to use the prototype, since I wanted my methods to be static. The code runs fine for the first 2-3 times, then after the 4th or so instance of Slideshow, it fails.

Any ideas?
