The ResourceModel and ResourceItemModel classes are [Bindable]. Is that what you're talking about?
Also, I was thinking that the 'selected' property of ResourceItemModel is not used for the 'selected' property of the CheckBox in the itemRenderer. The 'label' property of the model seems to work, but is 'selected' not the appropriate variable to use?
