javascript - angularjs 过滤器(不工作)

Question

以下 HTML、Javascript 和 JSON 正确呈现，但过滤器根本不起作用。我们做错了什么？

<div data-ng-controller="dashboard_controller">
    <h1>
        Catalogs
        <input type="text" data-ng-model="catalog_filter" placeholder="Filter Distributors">
    </h1>

    <div class="catalogs_listing">
        <ul data-ng-repeat="catalog in catalogs | filter:catalog_filter">
            <li><a href="{{catalog.distributor_id}}/d/products/catalog_view/{{catalog.uid}}">
                <div class="catalog_thumb">
                    <div class="catalog_thumb_image">
                        <img src="{{catalog.thumb_image}}" />
                    </div>
                </div>
                <div class="catalog_info">
                    <h2>{{distributors[catalog.distributor_id].name}}
                        <span>{{catalog.products_count}}p</span>
                    </h2>
                    <p>{{catalog.name}}</p>
                </div>
                </a>
            </li>
        </ul>
    </div>
</div>

Javascript:

app.controller('dashboard_controller', function ($scope, $http) {
    $http.get('./api/distributors/my').then(function (res) {
        $scope.distributors = res.data;
    });
    $http.get('./api/dashboard/catalogs').then(function (res) {
        $scope.catalogs = res.data;
    });
});

还有这 2 个 JSON:
