Your approach should work. The issue you're encountering is your use of this in your onchange event is invalid. Try replacing your this.form references with something like this:

<%= Html.DropDownList(

        new { onchange = @"
            var form = document.forms[0]; 
            form.action='MyMethod';
            form.submit();" 
        } ) %>
