Eu escrevi uma diretiva para caixas de diálogo (myPopup) e outra para arrastar essa caixa de diálogo (myDraggable), mas sempre recebo o erro:

Várias diretivas [myPopup, myDraggable] solicitando um escopo novo / isolado

Aqui está um Plunker:http://plnkr.co/edit/kMQ0hK5RnVw5xOBdDq5P?p=preview

O que eu posso fazer?

Código JS:

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

function myController($scope) {
    $scope.isDraggable = true;
}


app.directive('myPopup', [
    function () {
        "use strict";

        return {
            restrict: 'E',
            replace: true,
            transclude: true,
            template: '<div my-draggable="draggable"class="dialog"><div class="title">{{title}}</div><div class="content" ng-transclude></div></div>',
            scope: {
                title: '@?dialogTitle',
                draggable: '@?isDraggable',
                width: '@?width',
                height: '@?height',
            },
            controller: function ($scope) {
                // Some code
            },
            link: function (scope, element, attr) {
                if (scope.width) {
                    element.css('width', scope.width);
                }

                if (scope.height) {
                    element.css('height', scope.height);
                }                    
            }
        };
    }
]);

app.directive('myDraggable', ['$document',

                $event.preventDefault();
            }

            function mouseup() {
