HTML

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.1.5/angular.js"></script>
<div ng-app="MyApp" ng-controller="MyCtrl">
  <div ng-if="showOnCondition">
    <label ng-repeat="item in repeatingItems">
      {{item}}
      <setting item="item" />

  </div>
  {{checkSetting()}}
</div>

JavaScript

var myApp = angular.module('MyApp', []);

myApp.controller('MyCtrl', function($scope) {
  $scope.settings = {
    someProperty: '',
    anotherProperty: 'Hello'
  }

  $scope.repeatingItems = [
    'One',
    'Two',
    'Three'
  ];

  $scope.showOnCondition = true;

  $scope.checkSetting = function() {
    // When calling checkSettings(), I would like to access the value of someProperty here
    return $scope.settings;
  }
});

myApp.directive('setting', function() {
  return {
    restrict: 'E',
    require: '^myCtrl',
    // HOW DO I SOLVE THIS?
    // $parent.$parent is bad.
    template: '<input type="radio" ng-model="$parent.$parent.settings.someProperty" name="mySetting" value="{{item}}" />',
    scope: {
      settings: '=',
      item: '='
    }
  };
});
