how to reset model/form create data

[rooney]

Hi, i have problem with create and update data, if i creating data and after that updating data, model/form create data is before will be running again, so data always added when update data.
this my script :

dataSource = new kendo.data.DataSource({

   transport: {

      read: {url:"<?=base_url()?>/bank"},

      update: {url:"<?=base_url()?>/bank/update", type:"POST"},

      destroy: {url:"<?=base_url()?>/bank/destroy",type:"POST"},

      create: {url:"<?=base_url()?>/bank/create",type:"POST"},

   },

   error: function(e) {

      alert(e.responseText);

   },

   batch: true, pageSize: 25,

   schema: {

   model: {

      id: "id_bank",

      fields: {

         nama_bank: { type: "string" },

      }

   }

}

});

//kendo grid

$("#grid_bank").kendoGrid({

   dataSource: dataSource,

   editable:  "popup", height: 450, filterable: true, sortable: true, pageable: true,

   toolbar: ["create"],

   columns: [

      { field: "nama_bank",title: "Nama", filterable: true },

      { command: ["edit", "destroy"], title: " ", width: "160px" }

   ]

});

i think a solution is function parameterMap, but i don't know for using that

thank you before
