Issue using custom component template

[hbaldwinRPT]

After doing some work to get a select component working, I'm having some issues getting the template to work. It worked great with the rating, but when I changed the HTML to my own, it stopped doing anything.

I guess I'm asking how to make a custom template available to the builder/renderer. the file names have all remained the same etc. but it still won't grab the template anymore. and if i try to pass it as the template option i get:

Unknown template: app-test-component
