How do you submit a dropdownlist in asp.net mvc from an Ajax form

Question

How do you submit from a dropdownlist \"onchange\" event from inside of an ajax form?

According to the following question: How do you submit a dropdownlist in asp.ne

Answer 1

I had a button like this in my AJAX.BeginForm

  <button id="submitButton" type="submit"  class="btn" style="vertical-align: top"><i class="icon"></i> replace</button>

And onsubmit or the solution from Francisco didn't work (I still don't know why)

So I created an alternative:

  new { onchange = "document.getElementById('submitButton').click()" }
