Add new component/page in local/html

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.


Works for me, did you restart your webserver?
