Yes, i rewrote code for new container class inherited from default - it returns correct object now. Thanks for answer.

OOLua keeps a userdata cache, so if create and then store the instance in the container, from Lua, it will know the derived class. This is until the instance in no longer reachable in Lua and the gc has ran. When the gc is ran, the corresponding userdata entry is removed from the cache. I imagine you are, at this point, retrieving the instance from the container and the method returns a base instance hence it is a base instance in Lua. In C++, for the rare occasion you would need this, you would use a dynamic_cast yet OOLua has no such cast.
