ASP.NET MVC 中调用KindEditor4.1.5无法写入数据库啊发了2个帖啦

ASP.NET MVC 中调用KindEditor4.1.5无法写入数据库求救啊！发了2个帖啦！
前台代码：
    KindEditor.ready(function (K) {
        var editor1 = K.create('#BOOK_CATELOGUE', {
            cssPath: '/kindeditor/plugins/code/prettify.css',
            uploadJson: '/kindeditor/asp.net/upload_json.ashx',
            fileManagerJson: '/kindeditor/asp.net/file_manager_json.ashx',
            allowFileManager: true,
            afterCreate: function () {
                var self = this;
                K.ctrl(document, 13, function () {
                    self.sync();
                    K('form[name=example]')[0].submit();
                });
                K.ctrl(self.edit.doc, 13, function () {
                    self.sync();
                    K('form[name=example]')[0].submit();
                });
            }
        });
        prettyPrint();
    });
控件代码：

<textarea name="BOOK_CATELOGUE" id="BOOK_CATELOGUE" cols="100" rows="8" style="width:700px;height:200px;visibility:hidden;" runat="server"></textarea>

或者

<%=Html.TextArea("BOOK_CATELOGUE", "", new { @rows = "8", @cols = "100", @style = "width:550px;height:200px;visibility:hidden;" })%>

这两种都试过了，都无法插入SQL数据库里面

后台代码：控制器代码：

model.BOOK_CATELOGUE = Tools.nullObject2String(this.Request["BOOK_CATELOGUE"])

SQL中的插入语句代码： 

 public int insert(Object obj,string stock)
        {
            int flag = 0;
            string bookID = new GUID().ToString();
            List<string> sqls = new List<string>();
            BS_BookInfoModels info = (BS_BookInfoModels)obj;

            StringBuilder sql = new StringBuilder();

            sql.Append("insert into BS_BookInfo(")
               .Append("ID")
               .Append(",")
               .Append("BOOK_NAME")
               .Append(",")
               .Append("BOOK_PRICE")
               .Append(",")
               .Append("BOOK_IMGURL")
               .Append(",")
               .Append("BOOK_INTRODUCTION")
               .Append(",")
               .Append("BOOK_CATELOGUE")
               .Append(",")
               .Append("CATEGROY_ID")
               .Append(",")
               .Append("IS_PROMOTION")
               .Append(",")
               .Append("PROMOTION_PRICE")
               .Append(",")
               .Append("IS_SPECIAL")
