Rails asset pipeline + knockout.js
===

I'm trying to implement knockout.js in Rails 3.2.6. I'm using the Gem https://github.com/jswanner/knockoutjs-rails. 

I'm having trouble loading the ViewModel.

Here's my HTML for debugging

    <div data-bind="text: ko.toJSON(users)"></div>


Here's the JavaScript compiled from CoffeeScript. The file is `users.js.coffee` and is included in the asset pipeline via `//= require_tree .` in `application.js`

    (function() {
    
      jQuery(function() {
        var User, UserViewModel;    
        User = function(id, name) {
          var self;
          self = this;
          self.id = ko.observable(id);
          self.name = ko.observable(name);
          return self.followers_count_message = ko.computed(function() {});
        };
        UserViewModel = function() {
          var self;
          self = this;
          self.users = ko.observableArray([new User('1111', 'test name'), new User('1112', 'test name2')]);
          self.addUsers = function() {
            return self.users.push(new User('1113', 'test name'));
          };
          return self.addUsers();
        };
        ko.applyBindings(new UserViewModel());
        return alert('done');
      });
    
    }).call(this);

Upon loading, the div displays this: `[null,null,null]`

The odd thing is if I implement this in jsFiddle, it seems to work. See this: http://jsfiddle.net/netwire88/HXYHU/2/

Thoughts, ideas?
