I think the problem is your didn't concretely explain what your method entails and how it is any different from doing a plain HTML website or a Javascript one. Technically, there is a server, and a client, so what do you do exactly on the server and the client and how does it difference from other methods? It's like someone asking you how does AJAX works and your start discussing functional programming. It doesn't explain what AJAX is and how does it differ from plain server side rendering.
