Or if you want to be like the original example, where the form is 
global for all users, make the FormBuilder instance once, and always 
return the same thing. There's lots of ways you could do that, but the 
easiest way is:
-    def child_form(self, ctx):
-        return FormBuilder()
+    child_form = FormBuilder()
