Solve the following python programming problem given the following code:
def commit_manually(using = None) : 
    "
    Decorator that activates manual transaction control. It just disables
    automatic transaction control and doesn't do any commit/rollback of its
    own -- it's up to the user to call the commit and rollback functions
    themselves.
    " 
    def entering(using) : 
        enter_transaction_management (using = using) 
        managed (True, using = using) 
def exiting(exc_value, using) : 
        leave_transaction_management (using = using) 
return _transaction_func (entering, exiting, exiting) 

    
    

    Fix the buggy line: return _transaction_func (entering, exiting, exiting)
