Update on selection broken after 0.12.16?

I think 0.13 lost functionality to programmatically use selection indices? In 0.12.16, the code below will update the drop_down when I click on a row of the data_table. In 0.13, it does not. Am I not fully compatible with the relatively new Selection() functionality or perhaps there’s a bug in >=0.13?

Thanks,

Clarified here: https://github.com/bokeh/bokeh/issues/8014

Should use source.on_change(‘indices’, myfunc) instead.
