Using polymer components in my project

I am trying to use polymer components in my project (https://github.com/benkeen/polymer-country-region-selector). I am trying to add the file into my project but for some reason it does not seem to be reflecting the changes. I have :

'public/vendor/country-region-selector/source/crs.js',
 'public/vendor/country-region-selector/source/jquery.crs.min.js'

to my grunt file. I can see the data going into the core.min.js.

I then call the country generator using jade like this:

country-region-selector(countrydropdownname='c', regiondropdownname='r')

It does not appear to show the changes. Am I doing anything wrong?
