Node js server for Ember Data

I have the sample "todo" ember application working with LSAdapter; now i'm attempting to use the RESTAdapter and get the json data from node js;

In the Ember application i've done:

Todos.Store = DS.Store.extend({
  revision: 13,
  url: "http://127.0.0.1"
});



Todos.Todo = DS.Model.extend({
    title: DS.attr('string'),
    isCompleted: DS.attr('boolean')
});

And this is the main route handler:

Todos.TodosIndexRoute = Ember.Route.extend({
    model: function() {
        return Todos.Todo.find();
    }
});

In ember data documentation they say that this should send an http request GET to url/todos, so in this case to:

http://127.0.0.1/todos

So i've made a Server with node js:

dispatcher.onGet("/todos", function(req, res) {
    bind.toFile('tmpl/todos.tpl', {

            id: "1",
            title: 'Just a try',
            is_completed: "false"

    }, function(data) {
        res.writeHead(200, {'Content-Type': 'text/html'});
        res.end(data);
    });
});

It uses httpdispatcher and bind modules from npm, and works because if i type in the browser:

//url in the browser
127.0.0.1/todos

i get:

{ "todo": { "id": 1, "title": Just a try, "is_completed": false } }

But if i execute the app in the browser (URL: file:///D:/Works/Web%20Resources/EMBER%20MVC%20FRAMEWORK/Prova_App/index.html) the todo "Just a try" is not loaded; inspecting with chrome, in the console tab, i can read an error that says "Failed to load resource file:///D:/todos"

Can someone help to figure this out?
