PDF Forms with javascript

[#1]

Is it planed to implement the javascript functionality in pdf forms on mobile version in the same way like in desktop version?
If yes, is there any planed schedual for release?
I found in the forum only the solution to use the app PDF Expert. Works perfect. Is there any other app to use pdf forms with javascript? 

I have attached a very simplified example to show my intension.
Only two different incomes are implemented, which show different values in the table below.
