yes, obviously: the GObject does not know how to free the data for you.

what you want is g_object_set_data_full(), where you can pass a
GDestroyNotify function which will be called when the data is destroyed.

don't, unless the amount of data you're actually binding is small and
you know exactly how to manage its lifetime. what you should be doing is
creating a new GObject class and use OOP.
