How to create a datasource from existing datasource

[Dhananjay]

I have an existing datasource as following , 

var data;    

      data = new kendo.data.DataSource(

      {

          type: "odata",

          pageSize: 5,

          endlessScroll: true,

          scrollTreshold: 30,

          transport:{

                       read: {

                           url: "http://odata.netflix.com/Catalog/Titles",

                           dataType: "jsonp",

 

                           data: {

                               Accept: "application/json"

                           }

                       }

                   }

 

               });

I want to create other datasource from this data source. I tried 

var data1 = new kendo.data.DataSource({

                    transport: {

                                   read: data.data()

                                    

                                }

                          });

                 data1.read();

it is throwing exception then I tried 

var data1 = new kendo.data.DataSource({ read: data.data()});

               data1.read();

It is throwing exception in all case.  My req is to create a filtered datasource from existing datasource .

Thanks
