Getting Shuffle.js and filtering to work

Question

I am stumped. Got the masonry part set up but can't understand why filtering doesn't work. I've been through the script, compared to the one on the demo site, and I'm going nuts.

I'm using : https://github.com/Vestride/Shuffle and Bootstrap 3. This probably has nothing to do with Bootstrap.

Apparently, though not in the docs, the script http://benalman.com/projects/jquery-throttle-debounce-plugin/ is a dependency too:

So add:
