通过角度js对焦点进行角度完全加载数据

Question

我有一个带有Angular.js和实体框架的c＃MVC项目。 在我看来，我使用控制器进行自动完成 它运作正常。

当我专注于自动填充的文本框搜索时，我想加载下拉数据。

        app.controller("HomeController", ['$scope', '$http', function ($scope, $http) {
            $scope.countries = [];
            $scope.SelectedCountries = null;
            $scope.AfterSelectedCoutries = function (selected) {
                if (selected) {
                    $scope.SelectedCountries = selected.originalObject;
                }
            }

            $http.get("/Home/Get_Doctor").then(function (d) {
                $scope.countries = d.data;
                $timeout(function () {
                    var searchInput = document.getElementById('txtautocomplete');
                    searchInput.focus();
                }, 0);
            }, function (error) {
                alert('Failed');
            })

        }])

                            <div class="form-group">
                                <label for="title" class="col-sm-2 control-label">Doctor</label>
                                <div class="col-sm-10">
                                    <div ng-controller="HomeController">
                                        <div angucomplete-alt id="txtautocomplete"
                                             placeholder="Type Doctor name" pause="100"
                                             selected-object="AfterSelectedCoutries"
                                             local-data="countries" search-fields="Doctor_Name_Arabic"
                                             title-field="Doctor_Name_Arabic" minlength="1"
                                             input-class="form-control" match-class="highlight">
                                      
                                         </div>
