One-To-Many collection not updating

I have implemented a one-to-many birectional relationship. The class City maintains a collection of the instances of class Branch.
When i am doing any updates in the collection (like changed the branch address) and than calling merge on the City bean, the changes are reflected in the database.
But when i am removing an instance from the collection, and than calling merge on the City bean, its not deleting the branch from the db.
What's the reason? and how to fix it?
I agree. Here's the link:
