模型不会在AngularJS中从控制器更新到指令模板

Question

我已创建指令以使用自定义自动填充功能。

app.directive('autocomplete', function () {
    return {
        restrict: 'E',
        scope: {
            results: '=',
            getStrLength: '&',
            selectObj: '&'
        },
        templateUrl: 'shared/js/angular/directives/templates/autocomplete.html'
    };
});

这里是指令

的视图

<input class="custom-autocomplete" ng-model="keyword" ng-keyup="getStrLength({word: keyword})" type="text" />

<div id='custom-autocomplete' ng-if="results" >
    <div class="object" ng-repeat="(country, groups) in results.value">
        <b class='flags flag_{{country| lowercase}}'></b>{{results.countries[country]}}
        <div class='object-first-level' ng-click="selectObj({obj: group})" ng-repeat='(city, group) in groups'>
            {{group.name}}
        </div>
    </div> 
</div>

＆＃34; selectObj＆＃34;函数执行$ scope.keyword已更新，但在指令模板

中没有更改

这是从控制器点击的功能

$scope.selectObj = function (obj) {
        $scope.autocompleteReusuls = '';
        $rootScope.keyword = obj.name;
}
