Backbone delete command executes on the Node server but no sync event is fired on the frontend

After issuing delete command from Backbone sync, I am not getting sync event although Node server executes the command and deletes an entry from MongoDB. This is the relevant code on the frontend (Backbone):

handleDeleteCar: function (carId) {
  Backbone.sync("delete", cars.get(carId), {url:'/api/cars/' + carId});
  cars.remove(cars.get(carId));
},

and on the backend (Node):

app.delete('/api/cars/:id', function (req, res) {
  var carImage = Car.findById(req.params.carId)._carImage;
  Car.remove({ _id : req.params.id } , function (err){
    if (!err){
      console.log("Cars deleted");
      Image.remove({_id:carImage},  function (err){
        if (!err)
          console.log("Image deleted");
        res.json({"status":"O.K."});
      });
    }
  });
});

As I said everything works fine except I am not getting a sync event in the browser. I am getting this event for every other verb I am using (get, post and put). I tried with different return values from the server, but to no avail.

You shouldn't be using Backbone.sync directly. The correct way to do this is to set the collections url to '/api/cars/' and call model.destroy():

var Cars = Backbone.Collection.extend({
  url: '/api/cars/',
  /* ... */
});

/* ... */
handleDeleteCar: function (carId) {
  cars.get(carId).destroy()
}
