I am using Backbone.Marionette's CompositeView and I want to insert a new model at index 0 of the collection and have it appear as the first view in the composite.

I have this code to insert the element:

```
PlansApp.Plans.collection.unshift new PlansApp.Plan data

```

The problem is that the CompositeView ignores the index of the newly inserted item in the collection.

in Backbone.Marionette, the appendHtml method looks like this:

```
  appendHtml: function(collectionView, itemView, index){
    collectionView.$el.append(itemView.el);
  },

```

The index argument is never used.

The newly inserted view will always be placed at the end of the composite.

How can I get it to appear at position 0?
