在 Angular 中的控制器之间绑定数据

不确定我是否正确执行此操作。我有两个控制器。一个拉所有帖子。另一个给了我垃圾桶里所有帖子的计数。它目前有效，但只有一种方式。如果我从垃圾桶中撤消帖子并将其放回人口中，则计数会更改以反映新数字，但是如果我将帖子发送到垃圾箱，则计数不会更新。

这是我的服务：

app.service('sharedProperties', function () {
});

这是我的第一个控制器：（该控制器提供所有帖子并具有垃圾功能）

app.controller('postsCtrl', function ($scope, $log, $http, $timeout, Data, $uibModal, sharedProperties) {
    Data.get('posts').then(function(data){
        $scope.posts = data.data;
        $scope.currentPage = 1; //current page
        $scope.filteredItems = $scope.posts.length; //Initially for no filter  
        $scope.totalItems = $scope.posts.length;
        $scope.list_pages = [
                {
                    id: '5',
                    name: '5'
                }, {
                    id: '10',
                    name: '10'
                }, {
                    id: '20',
                    name: '20'
                }, {
                    id: '50',
                    name: '50'
                }, {
                    id: '100',
                    name: '100'
                }
            ];
        $scope.maxSize = 5;
    });
    $scope.setPage = function(pageNo) {
        $scope.currentPage = pageNo;
    };
    $scope.filter = function() {
        $timeout(function() { 
            $scope.filteredItems = $scope.filtered.length;
        }, 10);
    };
    $scope.sort_by = function(predicate) {
        $scope.predicate = predicate;
        $scope.reverse = !$scope.reverse;
    };
    $scope.changePostStatus = function(post){
        post.approved = (post.approved=="1" ? "0" : "1");
        Data.put("posts/"+post.id,{approved:post.approved}).then(function (result) {
            Data.toast2(result);
        });
    };
    $scope.changePostAnnounce = function(post){
        post.announce = (post.announce=="1" ? "0" : "1");
        Data.put("posts/"+post.id,{announce:post.announce}).then(function (result) {
            Data.toast2(result);
        });
    };
    $scope.trashPost = function(post){
        if(confirm("Are you sure to remove the post")){
            Data.delete("posts/"+post.id).then(function(result){
                $scope.posts = _.without($scope.posts, _.findWhere($scope.posts, {id:post.id}));
                $scope.totalItems = $scope.posts.length;
                Data.toast(result);
            });
        }
    };
    $scope.open = function (p,size) {
        var modalInstance = $uibModal.open({
          templateUrl: 'views/postsEdit.html',
          controller: 'postsEditCtrl',
          size: size,
          resolve: {
            item: function () {
              return p;
            }
          }
        });
        modalInstance.result.then(function(selectedObject) {
            if(selectedObject.save == "insert"){
                $scope.posts.push(selectedObject);
                $scope.posts = $filter('orderBy')($scope.posts, 'id', 'reverse');
            }else if(selectedObject.save == "update"){
                p.title = selectedObject.title;
                // p.price = selectedObject.price;
                // p.stock = selectedObject.stock;
                // p.packing = selectedObject.packing;
            }
        });
    };
});

这是我的第二个控制器：（这个控制器计算垃圾桶中的帖子）

app.controller('postsTrashCtrl', function ($scope, $log, $http, $timeout, Data, sharedProperties) {
    Data.get('trash').then(function(data){
        $scope.trash = data.data;
        $scope.totalTrashItems = $scope.trash.length;
    });
});

在控制器 1 中，垃圾发布功能是我尝试从控制器 2 更新总垃圾箱的地方

我知道这是我错过的小东西。

更新

具有控制器和变量的 HTML：

<div class="container">
        <div class="row" align="center">
            <div class="stats" ng-controller="postsTrashCtrl"><i class="fa fa-thumb-tack"></i> Total Posts (<span class="attendStat">{{ totalItems }}</span>)<span class="seperator">&nbsp;&nbsp;|&nbsp;&nbsp;</span><i class="fa fa-trash-o"></i> <a href="#/trash" id="trashCan" class="trashCan">Trash</a> (<span class="attendStat">{{totalTrashItems}}</span>)</div>
        </div>
