会话存储在刷新后保留值

Question

实际上我在sessionStorage中获得了一个值，但它不会在页面中注入。当我们刷新整个页面时，它会注入。

JavaScript代码：

ctrl.modelObject = $sessionStorage.associatedCspaList;

HTML代码：

<ul class="list-group">
    <li class="list-group-item" ng-repeat="cspa in ctrl.modelObject track by $index">{{cspa}}</li>
</ul>

associatedCspaList:["1111111111111111","1111222233334444","1111222244445555","1231123112311231","1234567891234567","1234567893216549"]
