To search for a data in JSONModel

Hi experts,

var oModel = new sap.ui.model.json.JSONModel({

businessData : [

{Country :"Canada",revenue:410.87,profit:-141.25, population:34789000},

{Country :"China",revenue:338.29,profit:133.82, population:1339724852},

{Country :"France",revenue:487.66,profit:348.76, population:65350000},

{Country :"Germany",revenue:470.23,profit:217.29, population:81799600},

{Country :"India",revenue:170.93,profit:117.00, population:1210193422},

{Country :"United States",revenue:905.08,profit:609.16, population:313490000}
