Looks like each created instance of FormWrapper is sharing the same
instance of the new_data dictionary. Instead of just referencing the
dictionary, try copying it:
new_data = dict(template.__dict__)
By the way, be really careful about accessing the __dict__ attribute
in Django code. Django sprinkles all kinds of interesting stuff into
its own objects, so you may sometimes get a surprise.
