ASP.NET MVC - how to get value from text field in my view?

Question

If I have a text box in my view:

<div><%= Html.TextBox("Comments", Model.Comments)%></div>

I want to publish the contents of this text box to the controller using an Ajax call. I need only one value, so I do not want to publish the whole form.

<%= Ajax.ActionLink("update", "UpdateComments", 
                new { comments = /* ????? */ }, 
                new AjaxOptions { HttpMethod="POST" })%>
