Modify Get Request of a Kendo UI treeview -

i'm having trouble kendo ui treeview, displays same node each time click go deeper tree.

my problem regular request looks this:

something/getchildren/3432fdsf8989/apr222014083453am 

when click next node request looks this:

something/getchildren/3432fdsf8989/apr222014083453am?identifier=2323eded7664 

and want have this:

something/getchildren/2323eded7664/apr222014083453am 

is possible change url kendo ui hierarchicaldatasource? web service ignoring identifier , still using initial id.

function inittreeview(date, targetid) { var requesturl = "something/getchildren/"+ targetid + "/" + date;  var datasource = new kendo.data.hierarchicaldatasource({     transport: {         read: {             url      : requesturl,             datatype : "json"         }     },     schema: {         model: {             id: "identifier",             haschildren: true, //all items may have children         }     } });  $("#treeview").kendotreeview({     datasource: datasource,     datatextfield: "message" });  } 

the url in transport definition can function. define function generates in proper / desired format.

transport: {     read: {         url: function(options) {             return something/getchildren/"+ targetid + "/" + date;         }     } }
