角度Js：图像滑块在范围更新后不起作用

Question

我试图以角度js显示图像幻灯片。当页面加载时，图像显示正常。我有一个搜索按钮（在页面的起始处将是一个默认字符串）当尝试搜索某些内容时，范围消失。我尝试调试，搜索发出一个http调用，正确返回输出，但绑定有问题。有人可以告诉我这里有什么问题吗？我尝试添加控制台，它使用控制台正确打印但未在ui或幻灯片中显示

<input class="form-control" style="width: 50%;margin: auto;" type="text" placeholder="Location"
                       no-special-char ng-model="customerLocation"
                       required>
                <button class="btn btn-default" type="submit" ng-click="searchLocation()">Search</button>

<div class="form-group col-md-5">
            <carousel interval="myInterval" no-wrap="noWrapSlides">
                <slide ng-repeat="slide in slides" active="slide.active">
                    <a href="{{slide.detailPage}}" target="_blank">
                        <img ng-src="{{slide.image}}" style="width:300px; height:400px; margin:auto;">
                    </a>
                    <div class="carousel-caption" style="color:black">
                        <p style="background:white">{{slide.text}}</p>
                    </div>
                </slide>
            </carousel>
        </div>

JS代码：

$http.get('/getCurrentLocation.do').success(      
        function (result) {
            var testing = [];
            var index = 1;
            for(var i = 0; i < result.length; i++) {
                var model = result[i];
                var title = {};
                title.id = index;
                title.text = model.title.title;
                title.size = model.count;
                title.image = model.titleImageURL;
                title.detailPage =  model.detailPage;
                title.active = (index == 1 ? true : false);
                index++;
                testing.push(title);
            }
            $scope.slides = testing;   ## works here
        });

    $scope.searchLocation = function() {
        searchForLocation();
    }

    function searchForLocation() {
        if ($scope.customerLocation != null) {

            $http.get('/getSearchLocation.do',
                      {params: {'searchLocation': $scope.customerLocation}}).success(
                        function (result) {
                            var testing = [];
                            var index = 1;
                            for(var i = 0; i < result.length; i++) {
                                var model = result[i];
                                var title = {};
                                title.id = index;
                                title.text = model.title.title;
                                title.size = model.count;
                                title.image = model.titleImageURL;
                                title.detailPage =  model.detailPage;
                                title.active = (index == 1 ? true : false);
                                index++;
                                testing.push(title);
                            }
                            $scope.slides = testing;   ## not working here though the testing has values
                        });
        }
    }

我认为与角度模型有关但无法弄清楚这里有什么问题
