How to access parent component in angularjs 1.5

To inherit with require, the components need to be nested:

<hello name="Parent"></hello>
<hello1 name="Child"></hello1>

instead do

<hello name="Parent">
    <hello1 name="Child"></hello1>
</hello>

Then you can require the parent like so:

require: {
    parent: '^^hello'
  },

Actually I got the answer after making following modification with the answer @gyc pointed:

JS CODE:

angular
    .module('componentApp', [])
    .controller('helloCtrl', function ($scope) {
        $scope.names = ['morpheus', 'neo', 'trinity'];
    })
    .component('hello', {
        transclude: true,
        template: '<p>Hello I am {{parentCtrl.name}} and my name is {{parentCtrl.myName}}</p><ng-transclude></ng-transclude>',
        controllerAs: 'parentCtrl',
        controller: function ($scope) {
            this.myName = 'Braid';
        },
        bindings: {
            name: '@'
        }
    })
    .component('hello1', {
        template: '<p>Hello I am {{$ctrl.name}} && my parent is {{myNameFromParent}}  </p>',
        controller: function ($scope) {
            this.$onInit = function () {
                $scope.myNameFromParent = this.parent.myName;
            };

        },
        bindings: {
            name: '@'
        },
        require: {
            parent: '^hello'
        }
    });

HTML:

<html>
<body ng-app="componentApp">
    <div ng-controller="helloCtrl">
        <hello name="Parent">
            <hello1 name="Child"></hello1>
        </hello>
        <label>List:
            <input name="namesInput" ng-model="names" ng-list=" | " required>
        </label>
    </div>
</body>
</html>

The common mistake I was doing it was not following the nested component format and not using transclude in my parent. The rest worked fine when I made these two changes and modified my subsequent code.

P.S - The ng-list included in HTML has nothing to do with components.That was for other purpose.

@gyc - thanks for the help.Your input helped.

@daan.desmedt - I was hoping for the solution in components not directives.
