Support for Angular 1.5.x

I am working on a project using angular 1.6.4 and on using the this directive it throws an error stating
TypeError: self.$http(...).success is not a function
at FontsService._initGoogleFonts (angular-fontselect.js:2917)
at new controller (angular-fontselect.js:1955)
at Object.invoke (angular.js:5003)
at S.instance (angular.js:10866)
at n (angular.js:9746)
at angular.js:10154
at angular.js:16832
at m.$digest (angular.js:17971)
at m.$apply (angular.js:18269)
at l (angular.js:12387)

Beyond angular 1.5+ the $http service no longer supports the .success()
