I can't make my collection display.
I have a REST controller in my backend '/cars' and this JS code at the page

```
var Cars = Backbone.Collection.extend({
    url: '/cars'
});
var myChildV = Marionette.View.extend({
    template: '#myV',
});
var myCollectionV = Marionette.CollectionView.extend({
    collection: new Cars(),
    childView: myChildV,
});
var collectionV = new myCollectionV();
collectionV.render();

```

but it displays nothing on page.
The template is placed before js is executed and looks like

```
<script id="myV" type="x-template/underscore">
    <h1><% items.name %></h1>
    <h2><% items.price %></h2>
</script>

```

I've tried to read some guides, newbie introduction book, but there all providing examples without REST controllers.
What should I do to display a collection of models?
