Solve the following python programming problem given the following code:
def comparable_using(comparator_factory) : 
    "Decorator, allow a Python @property to be used in query criteria.

    This is a  decorator front end to
    :func:`~sqlalchemy.orm.comparable_property` that passes
    through the comparator_factory and the function being decorated::

      @comparable_using(MyComparatorType)
      @property
      def prop(self):
          return 'special sauce'

    The regular ``comparable_property()`` is also usable directly in a
    declarative setting and may be convenient for read/write properties::

      prop = comparable_property(MyComparatorType)

    " 
    def decorate(fn) : 
        return comparable_property (comparator_factory, fn) 
return comparator_factory 

    
    

    Fix the buggy line: return comparator_factory
