Thanks @Don - I had a play with this and I think this is a better way of doing it, which should work with the new slider: https://github.com/VaperinaDEV/category-btn-name/pull/1 (sorry if I messed up any of the Hungarian). That kind of pattern should be useful if others need to update their components as well (using computed properties rather than didInsertElement and JQuery).
added to my list to investigate, thanks
