Passed object in post ajax

Passed object in post ajax

Hello. I'm trying to pass data. 
var favorite = {};
favorite[videobody.id] =  item.statistics;

So, at the moment i receive similar object:


Object{}
1

Object { viewCount= "88" , more... }



When I passed data to ajax and result is empty or non-existing object. 
$.ajax({
    url: "/admin/songs/ajaxViewers",
    type: "post",
    data: {favorite:favorite},
    success: function () {
       // location.reload();
    },
    error: function () {
        alert("PROBLEM");

    }
});

How to rewrite to work?
