DataSource with multiple schemas

[Omer]

Hi,

I have a page with 3 kendo grids that have the same datasource but with different schemas

right now i created 3 different datasources and it works except the fact that it calling the service 3 times

the service returns a json like this:

{"HomePageRes":{
  "Status":{
  "Error":"OK",
  "ErrorDesc":"",
              "UserError":"" 
              },
  "Call":  [  {
"No": 3697105,
"Type": "קריאה",
"Category":"עדכון ק\"מ",
"CarNo":"51-253-69",
"Model":"רנו מגאן 2  ביזניס ק", 
"DriverName":"שירי גולדשטיין",
"ApplicantName":"שירי גולדשטיין"} ],
"Fix":   [   ],
"Alert":  [{
"Deal":"",
"CarNo":"60-967-67",
"Model":"סובארו B3 סדן RX, או",
"DriverName":"אסף יוסף לחמיש",
"KM":0,
"Date":"20120731", 
"CollectionDate":"",
"Timestamp":"201206210737"
}]
}}

how can i call the service 1 time?
