Within our application we use a simple table. The users are allowed to add a row in this table. We want to translate the out of the box add button. 

Unfortunately, we have not been able to translate this button so far. We have implemented the translation in both the pygenericfields under SimpleTable localization rule and in the localization rule of the view of the table, but to no avail.

We see the translation in the json but the translation does not work. Does anyone know how to translate the add button? Thank you in advance!
