Lifecycle hook this.$postLink gives typeerror

I'm trying to learn angular 1.5 component and have stumbled into a problem. The following code is my startup layout of my component, which compiles without errors with my gruntjob.

angular.module('layout',[]).component('kiHeaderParallax',{
        controller: myController,
        controllerAs: 'comp',
        template:'<div>Yo</div>'
    });

    function myController(){
        this.$postLink(domManipulation);
        console.log('poop');
    }

    function domManipulation(){
        console.log('poop2');
    }


angular.element(document).ready(function() {
      angular.bootstrap(document, ['layout']);
    });

However I get this typeError when going to the browser:

> 1.angular-1.5.5.js:13550TypeError: this.$postLink is not a function

I am using Angular 1.5.5 - so that shouldn't be the issue - any ideas why I can't get my log through?

The solution

this.$postLink = domManipulation;

instead of

this.$postLink(domManipulation);
