MVC4，TinyMCE.MVC，无法在Ajax调用后设置TinyMCE控件内容

MVC4，下载的TinyMCE.MVC：需要通过Ajax调用检索TinyMCE控件的内容，并将其设置到该TinyMCE控件中。到目前为止，我在tinymce控件中设置html内容的尝试都失败了。我必须使用Ajax调用。有办法吗？ 多谢各位

视图：

我终于明白了： tinyMCE.activeEditor.setContentdata

<div id="divTinyMCE">
    @Html.EditorFor(model => model.myContent)
</div>
<button type="button" id="btnGetContent" onclick="getContent()">Get Content</button>

@section scripts{
<script type="text/javascript">

    function getContent() {

        var parm1 = 1;
        var parm2 = 2;

        $.ajax({
            type: "POST",
            url: '/Home/GetContent',
            data: { parm1: parm1, parm2: parm2},
            success: function (data) {                    
                alert("data from ajax = " + data.toString()); // data is html

                //tinymce.set(data.toString());  // does not set anything
                //tinymce.html(data);            // does not set anything
                $("#tinymce").html(data);        // does not set anything
            }
        });  // AJAX call

    }

</script>
}     

public ContentResult GetContent(int parm1, int parm2)
{
    string contentFound = findContent(parm1); // contentFound is HTML string
    return Content(contentFound);

}
