ajax form submit as usual form

I have some ajax form

 @using (Ajax.BeginForm("Action1", "Controller",
                                     new AjaxOptions
                                     {
                                         HttpMethod = "POST",

                                         UpdateTargetId = "content2",
                                         InsertionMode = InsertionMode.Replace,

                                     },
                                     new
                                     {
                                         id = "my_form",
                                         @class = "options_form",
                                         style = "height: 100%; width: 100%; "
                                     }))
    {
        <div id="content2">
            @Html.Partial("_FormPartial", Model)
        </div>
    }

And two buttons in my _FormPartial that calls two js functions

     function onAct1() {

           $('#my_form').attr('action', '@Url.Action("Action1", "Controller", new {area= "Test" })')
           $('#my_form').submit();
       }

        function onAct2(s, e) {



           $('#my_form').attr('action', '@Url.Action("Action2", "Controller", new {area= "Test" })')
 $('#my_form').submit();
        }

So for Act2 i want to use AjaxForm behavior byt for Act1 i want to make a simple page refresh and redirect to other page in controller.

So is there any way except changing form Url also change it behavior ?
