Angular One time binding still has watchers on it

Question

I used a simple AngularJS interpolation with one-time binding. The code works as expected and any further changes to that scope variable are not reflecting. However, when I was checking the performance of my application using Batarang (Chrome extension), I observed that there are still watchers left on that interpolation

I'm not sure if I really achieved any performance gain using one-time binding.

Answer 1

I came across several hints in the web, stating that Batarang would not work with one time bindings. Therefore I deinstalled Batarang and used angular watchers instead (for angular 1.3.x), worked like a charm.
