No worries j I will find the solution somehow, thnx for help anyway.

Saša Fišter np, sorry I can't be of more help. One last thought check the building process if you have the same behaviour if you use the compiled output instead the webpack build (I assume webpack). And if it still works locally maybe you can diff against the downloaded js compile files to see if there's a difference.

I found the bug. Initial value was in integer numbers, but when I cast it boolean, everything works perfectly. Something new every day :)
