Show loading message rendering counts

Fix #610
Signed-off-by: Sheik Hassan <solergiga@yahoo.com>
Why was this changed to trigger on all change events? This would result in unnecessary triggers when they occur when applying a filter. Since the view only renders a couple attributes, I would recommend only binding to those specific attributes including `change:count` and `change:object_name` (`object_name_plural` is in sync with the `object_name` so only one needs to be bound to).
