$ionicPopup/Sheetsu not working in API $http tutorial

Hi there! I was following along the weekly Creator workshop video on using APIs with angular $http (http://docs.usecreator.com/docs/using-apis-with-http-part-1) and have literally copy/pasted the code and followed the video (replacing the API url of course) and when I click the submit button it become permanently disabled and nothing pops up. The form information doesnt get logged onto my Google Spreadsheet/Sheetsu either. Help?
