Opportunity product customized subgrid stop work in 2016

Hi
In 2015 year and CRM 2015 I have a issue about disable opportunity product inline editing.
https://community.dynamics.com/crm/f/117/t/170653
At this moment the solution is simple. Create other subgrid in form with a diferent Name using a diferent view.
In this point every works fine (opening que opportunity product windows when + button was clicked).
Now this problem was changed. When the same organization was migrated to CRM 2016 the + button stopped work.
When attempt click in + button nothing is hapening (this is not a pop-up blocking).
I can't reactive the inline edit behavior.
I tried various approaches (ribbon workbench, views, names for grid). Nothing work.
Someone can help me ?
