templateUrl无法在angular指令中工作

Question

这是指令

 (function() {
        'use strict';

        angular
            .module('angle')
            .directive('tsDynamicDetailsList', tsDynamicDetailsList);

        tsDynamicDetailsList.$inject = ['$window'];

        function tsDynamicDetailsList($window) {
            // Usage:
            //     <ts_dynamic_details_list></ts_dynamic_details_list>
            // Creates:
            // 
            var directive = {
                link: link,
                restrict: 'E',
                templateUrl: 'app/views/partials/tsDynamicDetailsList.html',
                scope: {
                    singleItemName: '=',
                    list: '=',
                    snippetPartial: '=',
                    detailsPartial: '='
                }
            };
            return directive;

            function link(scope, element, attrs) {
            }
        }

    })();

我称之为：

<ts-dynamic-details-list singleItemName="'user'" list="users" snippetPartial="'userListSnippet.html'" detailsPartial="'userListDetail.html'"></ts-dynamic-details-list>

什么都没有加载。 tsDynamicDetailsList.html肯定存在。所有的建议都表示赞赏，提前谢谢。
