Right, and in other places it works for me. For instance, I have a window with text fields bound to a model object through an object controller. Updating properties of the model updates the text fields.
Reading your test below, one thing I was forgetting is that I am not binding a column in the table view to any specific property. I have one column bound to arrangedObjects and a custom cell that draws all the information (think Apple Mail with the subject line and then a snippet below). So, I guess it does make sense that the table view does not update. Perhaps reloadData after I change the item. The menu item's state property is bound to the archive property of selectedObjects. Seems like that should update appropriately. The only difference between that and your test is that I am not using an external array. I am just receiving the action from the menu item, then iterating over selectedObjects and changing the property on each.
