"Cannot read property 'apply' of undefined"

Iam getting the above error after getting the token in console. Line 793 of commit angular-payments#2472bc9befa25678

[VictorManuelSarmiento]

Replace (Line 793):
scope[attr.stripeForm].apply(scope, args);
for
scope.$eval(attr.stripeForm).apply(scope, args);

Check it!
