Cordova callback function与 angularjs ng-repeat双向绑定问题

    $scope.images_list = [];
    $scope.addFromAlbum = function() {
        plugins.imagePicker.getPictures(addFromAlbumSuccess, addFromAlbumFail, { maximumImagesCount: 10, quality: 100 });
    }
    function addFromAlbumSuccess(results) {
        for (var i = 0; i < results.length; i++) {
            var obj = {};
            obj.url = results[i];
            $scope.images_list.push(obj);
        }
        console.log($scope.images_list.length)//这里可以正确显示
    }
    function addFromAlbumFail(error) {
        console.log('Error: ' + error);
    }
    
    <------------------------------------>
    <div class="list">
            <div class="item">
                <img ng-repeat="img in images_list" style="width:60px;height:80px;" ng-src="{{img.url}}">
            </div>
     </div>
        
        测试发现Dom并没有刷新，没有数据显示；即双向绑定没起作用；和插件没有关系，只是在插件回调时没有触发双向绑定，更新dom;求解决？！
        答案：$apply
