Javascript 具有方向性的角模型

我试图将一个对象传递到一个指令中，然后该指令可以更新这个值。到目前为止，我有以下几点：

 <competence-select ng-model="module.selectedCompetence"></competence-select>

（请注意要求）

然后是我的指令html：

    <label translate="FORMS.COMPETENCES"></label>
<ui-select multiple reset-search-input="true" ng-model="competenceList" theme="bootstrap"
           ng-disabled="disabled">
    <ui-select-match placeholder="{{ 'FORMS.COMPETENCES_PLACEHOLDER' | translate }}">{{$item.name}}
        &lt;{{$item.competence_type_id == 1 ? 'Faglig' : 'Personlig' }}&gt;</ui-select-match>
    <ui-select-choices group-by="someGroupFn"
                       repeat="competence in competences | propsFilter: {name: $select.search, competence_type_id: $select.search}">
        <div ng-bind-html="competence.name | highlight: $select.search"></div>
        <small>
            {{competence.name}}
            {{ 'COMPETENCES.TYPE' | translate:{TYPE: competence.competence_type_id} }}
        </small>
    </ui-select-choices>
</ui-select>

设置此选项应将视图中的

ng模型设置为我在指令中设置的ng模型。从而将变量“up”解析为指令的声明：

<competence-select ng-model="module.selectedCompetence"></competence-select>



遗憾的是，情况并非如此

有人能告诉我我做错了什么吗？
在指令中做这些更改

angular.module('Competence').directive("competenceSelect", ['competenceService', function (competenceService) {
    return {
        restrict: "E",
        templateUrl: 'js/modules/Competence/directives/competence-select/competence-select.html',
        require: 'ngModel',
        scope:{ ngModel : "=" }, 
        link: function (scope, element, attr, ngModel) {
            ngModel.$setViewValue = scope.competenceList;
            scope.competences = [];


   competenceService.getCompetenceList().then(function (result) {
                scope.competences = result;
                scope.ngModel = scope.competences;
            })
        }
    };
}]);

显然，您需要调用
$render（）
来更新模型，而不仅仅是视图。只是在谷歌上搜索了一下，发现@floribon是我们需要调用的正确选项。$render（）
$setViewValue
是一个函数。@Maverick很高兴知道。请随时发布答案
<competence-select ng-model="module.selectedCompetence"></competence-select>

angular.module('Competence').directive("competenceSelect", ['competenceService', function (competenceService) {
    return {
        restrict: "E",
        templateUrl: 'js/modules/Competence/directives/competence-select/competence-select.html',
        require: 'ngModel',
        scope:{ ngModel : "=" }, 
        link: function (scope, element, attr, ngModel) {
            ngModel.$setViewValue = scope.competenceList;
            scope.competences = [];


   competenceService.getCompetenceList().then(function (result) {
                scope.competences = result;
                scope.ngModel = scope.competences;
            })
        }
    };
}]);
