Hi Nitish,
Try this code it works fine for me
oCon = new sap.ui.commons.TextField().bindProperty("value",
{path: "CONFIRMED_DATE",
formatter: function(oValue){
if (oValue) {
var oDt = new Date((parseInt(oValue.substr(6))));
return sap.ui.core.format.DateFormat.getDateInstance(
{style:"full", pattern: "MMMM d, yyyy"}).format(oDt);
}
}});
