I'm using scopeless directives (https://github.com/johnpapa/angularjs-styleguide#directives-and-controlleras).
<directive1>
<directive2></directive2>
</directive2>
In outer directive1 I've got controllerAS: 'vm' with var vm=this; vm.test="test from directive1" in it.
Inner directive2 has scope: false, controllerAs: 'vm2', bindToController:true
How from directive2 get directive1 vm.test data? I want to use it in controller - not HTML view
