删除绑定和CK编辑器工具栏不显示

我是全新的敲出自定义绑定，我正试图将ckeditor与敲出绑定集成，我有以下绑定从谷歌搜索，

    ko.bindingHandlers.wysiwyg = {
        init: function (element, valueAccessor, allBindingsAccessor, viewModel) {
            var value = valueAccessor();
            var valueUnwrapped = ko.unwrap(value);
            var allBindings = allBindingsAccessor();
            var $element = $(element);

            $element.attr('contenteditable', true);
            if (ko.isObservable(value)) {
                var isSubscriberChange = false;
                var isEditorChange = true;
                $element.html(value());
                var isEditorChange = false;
                $element.on('input, change, keyup, mouseup', function () {
                    if (!isSubscriberChange) {
                        isEditorChange = true;
                        value($element.html());
                        isEditorChange = false;
                    }
                });
                value.subscribe(function (newValue) {
                    if (!isEditorChange) {
                        isSubscriberChange = true;
                        $element.html(newValue);
                        isSubscriberChange = false;
                    }
                });
            }
        }
    }

我有以下代码要绑定，

$(function () {
    $.getJSON("/getdata", function (data) {
            ko.applyBindings({
                testList: [{
                    test: ko.observable()
                },
                {
                    test: ko.observable()
                }]
            }, document.getElementById('htmled'));
    });
});

HTML如下

 <div id="htmled" data-bind="foreach:testList">
                 Data
     <div class="editor" data-bind="wysiwyg: test">Edit this data</div>
 </div>

当我调用ko时，绑定工作并显示工具栏。$之外的applyBindings。getJSON方法。但当我在内部调用applyBindings时，工具栏没有出现。有人能帮我吗?我肯定是遗漏了什么，任何帮助都是非常感谢的。
