It seems like I can't access certain part of my page. To verify i tried $("form").html("these forms I could find");
I use extension by IWD Agency, but I believe this has nothing to do with their module.
When editing JS inside module you can see that only Search bar and Payment Selection could be change, other forms remain unchanged.
When editing JS from my custom module I can change only Search Bar.
I guess this is caused by AJAX that forms are not loaded when the script runs. Any ideas how could this be changed?
