I want to create a local/html/Helpers/AddToMyCustomField handler page, which reacts to ajax calls and do some stuff.
If I try to navigate to this page in my browser it says such page does not exist. Must component or page be present in share/html folder in order to be able to customize it in local/ folder?
Developer mode is on and web server restarted.
Is there any workaround as I would want to add new functionality using local folder.
