Does call_backs with same name in parent and child classes need not to be called again

I had two methods with same name which is present in both parent and child class. But I the callback before_filter: method_name is called only in parent class and the before_filter: is not present in child class. But load_object is called in child class without call_back itself.

class Parent

before_filter: call

def call // end

end

class child < Parent

def call //But the method is called here without call_back end

end

There is no class is inherited from child.
