I'm trying to get a simple ASP.NET web form working with a ScriptService. I used something similar several years ago but can no longer compile the original source. I've made a more simplified example but script service class's function is never getting called.
Below is a link to the project. It was made in VS2017.

Obviously I'm missing something but I don't know what. Any help would be appreciated. Thanks.
