AngularJS将指令模板中的参数传递给控制器

.directive('nodeList',function($compile) {
    return {
        restrict: 'E',terminal: true,scope: {
            nodes: '=ngModel',deleteArticle: '&',editArticle: '&'
        },link: function ($scope,$element,$attrs) {
            if (angular.isArray($scope.nodes)) {
                $element.append('<accordion close-others="true"><node ng-repeat="item in nodes" ng-model="item" delete-article="deleteArticle(node_item)" edit-article="editArticle(node_item)"></node></accordion>');
            } 
            $compile($element.contents())($scope.$new());
        }
    };
})

.directive('node',scope: {
            node: '=ngModel',$attrs) {
            if (angular.isArray($scope.node.Options) && $scope.node.Options.length > 0) {
                $element.append('<accordion-group><accordion-heading>{{node.Title}}   <a href="javascript:void(0)" ng-click="editArticle({node_item: node})" data-toggle="modal" data-target="#new-article" class="action"><i class="glyphicon glyphicon-edit"></i></a></accordion-heading><node-list ng-model="node.Options"></node-list>{{node.Content}}</accordion-group>');
            } else {
                $element.append('<accordion-group><accordion-heading>{{node.Title}}   <a href="javascript:void(0)" ng-click="editArticle({node_item: node})" data-toggle="modal" data-target="#new-article" class="action"><i class="glyphicon glyphicon-edit"></i></a></accordion-heading>{{node.Content}}</accordion-group>');
            }
            $compile($element.contents())($scope.$new());
        }
    };
})

和这样的HTML：

<node-list ng-model="articles" delete-article="deleteArticle(node_item)" edit-article="editArticle(node_item)"></node-list>

在控制器中：

$scope.editArticle = function(vArticle) {}

当我只有一个指令 – 一切都很清楚,但是当我的指令调用另一个指令时如何传递参数？这是真的吗？如何？
