Email Subscribe widget doesn't work on parrot theme

Hello,

I'm having problems with putting in the subscribe by email widget into one of my sites. The website URL is http://www.callbacklab.com

As you can see the follow button works fine when forced dynamtically into the site.

However the widget I had created, does nothing. When I click subscribe it just spins forever.

Dev console reveals that it calls upon admin ajax and stops there.

Any suggestions?
