Knockout.js没有从动态ajax调用更新视图

Question

我试图让knockout.js在ajax调用后更新我的视图,但没有运气.我一直收到下面的错误.它出错了app.interactive.updateBindings.parseBindingAttribute viewModel参数未定义.

错误:

无法解析绑定属性.消息:
ReferenceError:interactive未定义;
属性值:template: { name: 'answerTmpl', foreach: interactive.answers }

动态HTML:

<div id="questions">
    <div id="answers" data-bind="template: { name: 'answerTmpl', foreach: interactive.answers }">
    </div>
</div>

<script type="text/javascript">

    app.viewModel.interactive.answers(@Html.Raw(@Model.Answers.ToJson()));
    app.interactive.updateBindings(document.getElementById('answers'));

</script>
<script id="answerTmpl" type="text/html">
<div>
  <span></span>  <input type="checkbox" name="Answer" />
</div>
</script>

我的.js文件:

(function (app, $, undefined) {

    app.viewModel = {};
    app.interactive = {};
    app.interactive.callback = function () { };

 app.viewModel.interactive = {
        content: ko.observable('test'),
        answers: ko.observableArray()
    };

        app.interactive.init = function () {

        ko.applyBindings(app.viewModel);
    };

    app.interactive.updateBindings = function (element) {
        ko.applyBindingsToNode(element);
    };

    app.interactive.init();

})(window.app = window.app || {}, jQuery);

我可以使用以下代码修复:

ko.applyBindingsToNode(element, null, app.viewModel);

但是现在我收到了这个错误:

'in'operand jQuery.template无效

if (templateId in jQuery['template'])

我觉得自己像个白痴.我甚至没有引用jquery模板脚本.
