Sorted :
Looks like BB OS5 has problem with jQuery-Ajax.. For someone who is trying the same try using XMLHttpRequest.
$("#homePg").on('pageinit', function(event) {
var url = serviceURL+'testgroups'
http.open("GET", url, true);
http.onreadystatechange = function() {//Call a function when the state changes.
if(http.readyState == 4 && http.status == 200) {
//alert(http.responseText);
var json = JSON.parse(http.responseText);
$.each(json, function(i, object) {
var cr = "<li id='menuList'><a id="+object.id+" data-transition='slide' class='menuClass' ><img src=css/images/"+object.id+".png /> <h3> "+object.menuname+" </h3></a></li>";
$("#mainMenu").append(cr);
$("ul").listview("refresh");
$.mobile.hidePageLoadingMsg();
mainloaded = true;
});
}
}
http.send(null);
});
