the "_orderdetaillist" have form named "orderdetailform".when submit orderdetailform's button, want send data action , return "_orderdetaillist" has bootstrap grid. want load "_orderdetaillist" in main form without refreshing page.

main form:

@using (html.beginform(null, null, formmethod.post, new { role = "form" ,id="mainform"})) {         @html.antiforgerytoken()         @html.validationsummary(true)     /////some helpers...  <div class="clr"></div>    <div id="stufforderdetail">     @html.partial("_orderdetail")    </div>  <div id="stufforderdetail">  @html.partial("_orderdetaillist")         </div>  <div class="box-footer">             <input type="submit" value="ثبت" class="btn btn-primary" />         </div>      } 

_orderdetail partialview:

    @using (html.beginform(null,null, formmethod.post, new { role = "form", @id = "orderdetailform" })) {     @html.antiforgerytoken()     @html.validationsummary(true)  //some fields...    <div class="box-footer">           <input type="submit" id="orderdetailaddbtn" value="اضافه" class="btnbtn-success" />         <input type="button" id="orderdetaildeletebtn" value="حذف" class="btn btn-danger" />      </div> 

scripts:

<script src="~/scripts/jquery-1.11.1.min.js"></script> <script>    $("#orderdetailform").submit(function (ev) {     $.ajax({         url: '@url.action("addorderdetail", "orders", new { area = "adminsarea" })',                 type: 'post',                 success: function (result) {                     $("#stufforderdetaillist").html(result);                 }             });         ev.preventdefault();   //      return false;     });   </script>   @scripts.render("~/bundles/jqueryval") 

actions:

 [httppost] public actionresult addorderdetail(orderdetailviewmodel orderdetail)     {         list<orderdetailviewmodel> orderdetaillist = new list<orderdetailviewmodel>();   ////some code....          return partialview("_orderdetaillist", orderdetaillist);     } 

when click on "_orderdetail" submit button, mainpage refreshed , not action. how can solve that? thanks...
