javascript - Passing data from jQueryUI dialog form to controller -

i'm new asp.net/javascript , i'm having little trouble implementation of simple crud operations using jqueryui dialog form. code:

<button class="update" id="@model.id">update</button> <div id="dialog-form" title="update">   <form>     <fieldset>       <input type="text" name="state" id="state">       <input type="text" name="note" id="note">       <input type="submit">     </fieldset>   </form> </div>  <script>       $(function() {           var dialog,             state = $("#state"),             note = $("#note"),             id = this.id, //??             dialog = $("#dialog-form").dialog({               autoopen: false,               height: 400,               width: 350,               modal: true,               buttons: {                 "ok": function() {                   $.ajax({                     type: "post",                     url: "@url.action("update","ticket")",                     data: {                       id: id,                       state: state,                       note: note                     },                     cache: false,                     datatype: "json",                     success: function(data) {                       $("#dialog").dialog("close");                     }                   });                 },                 "cancel": function() {                   $(this).dialog("close");                 }               }             });            $(".update").button().on("click", function() {             dialog.dialog("open");           });         }); </script>     

finally update action in ticketcontroller:

  public actionresult update(string id, string state, string note)     {         //do stuff     } 

however nothing happens , doesn't action. appreciated

change data below need pass value rather object using .val()

state = $("#state").val(), note = $("#note").val(), id = "pass wants"  data: { 'id':id,'state':state,'note':note }, 

decorate action method [httppost]

[httppost] public actionresult update(string id, string state, string note) { }
