[Zope] How to set default permissions for objects in extern product

Hi, I want default permission settings for my object, which is an external product. I'd like, when people add my object to their folder, the object has already created the appropriate custom roles, and associated with them the appropriate permissions. I've tried to add a line 'self.manage_roles("member", "View management screens")' to the __init__ method of my object, but it doesn't work. Any idea?
