# When a list of customer is filtered and we removed the "filtered value" from a customer, we
# want to make sure the customer is updated. IE. filtering by tag, and removing said tag.
# Deleting the "filtered value" from a customer will remove the customer entry, thus
# removing "objForUpdate" directive from the active scope. That means $watch won't pick up
# the attribute changed.
# To ensure the customer is still updated, we check on the $destroy event to see if
# the attribute has changed, if so we queue up the change.
