Fix Uncaught TypeError: Cannot read properties of null (reading 'app_obj') when clicking a project title.

onclick for nextmatch rows was not getting re-parsed for each row, so it was trying with the original widget from the template instead of the one from the row.
Also accepting widget as argument into compiled legacy code and using it over original context so we don't need to re-compile for each row.
