角访问子component（）v1.5中的方法

Question

I'm using angular v1.5 and changing from directives to component() and I'm facing a situation

I have this component hierarchy grandfather > father > grandson and I'm trying to make a method available inside grandson component() so I'm passing the method from grandfather through grandson but this doesn't work, someone can give me a clue? maybe show me what I'm doing wrong? :/

I put a bit of code here to explain what I'm doing: https://gist.github.com/WagnerMoreira/29ca7764eaa335784e06eccf8b0223cf

Typically it can be done using require and, optional, $onInit like so:

require: {
    parent: '^nameOfParent'
}

Then in the controller that is making use of the inherited function you can initialize it like this:

vm.$onInit = init();

function init() {
    vm.foo = vm.parent.foo();
}
