Manage navbar buttons in ion view properties in RC

Hello,

Inspired by this Codepen : http://codepen.io/calendee/pen/JdtuG
I tried the same in RC version (the last one). But, I can’t make the button in the navbar appear.

How can you change or define a button in the navbar using an ion-view ? Is it possible ?

Thanks
