Hi your handlebar reference in the index.html file seems broken (line 39), you can update it with
https://cdnjs.cloudflare.com/ajax/libs/handlebars.js/4.0.5/handlebars.js
I've forked to try and seems to work as expected (usually i would make a pull request but gist don't support them), thanks for the example anyway!

Hey I am newbee to use this, with database record of relations how to use in asp.net.
Can you help on this?
Thank you
