Multiple directives [myPopup,myDraggable] asking for new/isolated scope

这是一个Plunker：http://plnkr.co/edit/kMQ0hK5RnVw5xOBdDq5P?p=preview

我能做什么？

JS代码：

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',['$document',function ($document) {
    return {
        restrict: 'A',replace: false,scope: { enabled: '=myDraggable' },elm,attrs) {
            var startX,startY,initialMouseX,initialMouseY;

            if (scope.enabled === true) {
                elm.bind('mousedown',function ($event) {

                };
            }

            function mousemove($event) {
                var x = startX + $event.clientX - initialMouseX;
                var y = startY + $event.clientY - initialMouseY;
                var limit = getMaxPos();
                x = (x < limit.max.x) ? ((x > limit.min.x) ? x : limit.min.x) : limit.max.x;

            }
        }
    };
