I am trying to return a model object from spring mvc controller back to jquery ajax method but it is returning blank as the response

jsp:

$( "#dialog-link10" ).click(function( event ) {
var appname= $("#dialog-link10").text();
alert(appname);
if(appname == 'RS Applications') {
$.ajax({
    type : "GET",
    url : 'abc.html',
    dataType: 'JSON' ,
    data: 
        {"id" : $("#dialog-link10").text()}
    ,
    success : function(data) {
        alert('success')
        alert('data')

    }
});}

controller:

@RequestMapping(method=RequestMethod.GET, value="/abc")
@ResponseBody
public  Model helloWorld2( @RequestParam("id") String id, Model model) {

    System.out.println("*****"+id);

    List  list1=new ArrayList();
    List  list2=new ArrayList();

        System.out.println("here");

        list1.add("abc");
        list1.add("abc2");
        list1.add("abc3");
        list1.add("abc4");

        model.addAttribute("list1", list1);

        return model;
        }

This is not generating success alert as well. Please suggest
