MVC3中的自ajax部分视图

I have a partial view inside a div with id 'rating'. So I have a ajax link inside the same partial view. So when I click on the link its updating one time and if i click the link second time, its loading the div two times and clicking three times load multiple times.

Anybody have the same issue?

<div class="rating"> 
  @Ajax.ActionLink("Flag this review as inappropriate", "CourseRatingFlag", "Content", new { cID = Model.courseRatings[index].crid}, new AjaxOptions() {  HttpMethod = "POST",TargetId="rating" })
some content...
  </div>

There is a similar question here.

In my case, I resolved it locating the target div out of the partial view.
