How do I trigger the success callback on a model.save()?

this.model.save({
  success: function(model, response){
    console.log('success');
  },
  error: function(){
    console.log('error');
  }
})

The model is correctly posted to the server which handles the save, but the success callback is not fired. Do I need to send something back from the server ?

The first argument of save is the attributes to save on the model:

this.model.save( {att1 : "value"}, {success :handler1, error: handler2});

For some unknown reason, none of the above method worked for me. The api only was not hit in my case.

But later while searching on this, I bumped into this link, where some one had tried null instead of {} as the first parameter.

this.model.save(null, {
    success: function (model, response) {
        console.log("success");
    },
    error: function (model, response) {
        console.log("error");
    }
});

so, this worked for me. Hope this helps you too.
