asp.net mvc ajax post from javascript

Following example demonstrate how to submit form in asp.net MVC for strict type view based on model:
(view has this instruction oin top:
@model MyModel
):

javascript part:

      
<script type="text/javascript"> 
    $(document).ready(function() { 
        $("#GoButton").click(function() { 
            var frm = $(this).closest('form'); 
            var params = frm.serialize(); 
             $.ajax({ 
                                type: 'POST', 
                                url: '@Url.ApplicationAction("MyPostAction", "myController")', 
                                data: params, 
                                cache: false, 
                                success: function (data) {                                     
                                  alert('Completed');  
                                }, 
                                error: function (xhr, data, message) { 
                                    //console.log(data + ": " + message); 
                                }, 
                                dataType: "json" 
                            }); 
            return false; 
        }); 
    }); 
</script> 

on server side model variable will have updated with all values submitted in form and will have following parameters:

 
[HttpPost] 
public ActionResult MyPostAction(MyModel model) 
{ 
 
 return Json("Ok"); 
}
