If you look at the top of the defintion (for example, 'def gr_hier_block2_sptr, [attribute], [another attribute]'), that's where you should find .set_callback. If it's not there, you'l just need to add it to the end; if it is there, then the attribute is probably given a different name somewhere else (so you'll just need to find out its new name and update the existing entry).
