LoadingTemplate is not working

When a user tries to initiate "Forget Password", I need show "loading" till "forget password" mail send. But "loading" template is not showing. It is not showing for any of our actions such as "signup, signin" etc. Below is my router config.

> Router.configure({
>     layoutTemplate: 'masterLayout',
>     loadingTemplate: 'loading',
>     notFoundTemplate: 'pageNotFound'
> });
