我有这样的代码，我需要用的CKEditor连接：Knockoutjs + CKEDITOR需要帮助您计算出来的东西
基本上我试图做的是把它与数据绑定的是已经存在通过连接：
textarea autocomplete="off" class="form-control" data-bind="rev_ckeditor, value: app.models.userReview.body" id="editor" maxlength="50000" name="body" cols="50" rows="10"
上面的textarea同时具有值data-bind和ckeditor的data-dind。但是ckwditor显示出来了，但不是数值绑定的值，是不是有什么问题？
代码：
(function($) {
'use strict'
app.viewModels.reviews = {
/**

*
* @type ko.observable(Array)

sourceItems: ko.observableArray([]),
