 This works automatically, so most of the times you don't need to know how it works. See the [DTO document](../../Data-Transfer-Objects.md) if you want to learn more about `IPagedAndSortedResultRequest`, `IPagedResult` and other standard interfaces and base DTO classes those are used in client to server communication.
 
+The `createAjax` also supports you to customize request parameters and handle the responses.

+var inputAction = function () {
+    return {
+        id: $('#Id').val(),
+        name: $('#Name').val(),
+    };
+};

+var responseCallback = function(result) {

+    // your custom code.

+    return {
+        recordsTotal: result.totalCount,
+        recordsFiltered: result.totalCount,
+        data: result.items
+    };
+};

 ### Row Actions
