Error in loading items in alfresco YUI datatable

[vicky]

I am using alfresco 5.0.d version needs to populate the custom model properties in YUI datatable and in response I am getting the JSON as below.
  {"agency" : [
                    {
                        "agencyname": "1212",
                        "agencycode": "1212",
                        "createDate": "23/03/2016"
                    }
                ]
        }

                                   var an = [
