Trying use express-load and express 4

I'm beginning in NodeJS, but my code have a problem. I'll show the code.

I need load the application in MVC pattern, I'm using the express-load, but it gives error when I create the load order.

app.js (The important part)

var load = require('express-load');
...
load('models').then('controllers').then('routes').into(app);

controllers/home.js

module.exports = function(app){
    var HomeController = {
        index: function(req,res) {
            res.render('home/index');
        }
    }

    return HomeController;
}

routes/home.js

module.exports = function(app){
    var home = app.controllers.home;

    app.get('/home',home.index);
}

Error

Because not even use models, modified the load

load('controllers').then('routes').into(app);

The controller and routes exists, but give error. I want load my app in MVC pattern.
