itemViewClassBinding in a collectionView
===

I'm trying to create a reusable component which consist of a textfield and under the textfield, i want to have a collectionView to display a filtered list of elements.

My problem is that I want itemViewClass of the containerView to be customized when creating the component. Currently, I pass a parameter listItemView to the container view and declare
itemViewClassBinding: 'parentView.listItemView' instead of having an hardcoded templates.

This leads me to a problem where Ember assert that itemViewClass must be an instance of Ember.View:

Uncaught Error: assertion failed: itemViewClass must be a subclass of Ember.View, not function () {

Did anybody ran into a similar problem?

Thank you
