Backbone.Marionette ItemView triggers

sample.js

// Model
module.SampleModel = Backbone.Model.extend({});

// View
module.SampleView = Backbone.Marionette.ItemView.extend({
  template : template_string,

  // This trigger runs only the first time. After that, "click" event is not triggered (defaults to href="#")
  triggers : {
    'click .reload' : 'reload'
  },

  initialize : function() {
    this.bindTo(this.model, "change", this.modelChanged);
    this.model.fetch();
  },

  modelChanged : function() {
    // App has a Marionette.Region called "mainRegion"
    App.mainRegion.show(this);
  }
});

// Init
var model = new module.SampleModel();

var view = new module.SampleView({
  model : model
});

view.on('reload', function() {
  console.log('reload event');
  model.fetch();
});

and thank you! i really appreciate that :)

Are you sure that the event on the model is "sync". It does not trigger when doing it this way:

var weatherModel = new module.WeatherModel({});

var weatherView = new module.WeatherView({
    model : weatherModel
});

weatherModel.on('sync', function() {
    App.mainRegion.show(weatherView);
});

weatherModel.fetch();

Data is fetched from the server (checked on browser console). If I use "all" on model event, the callback is executed many times, but not when using just "sync".

I'm looking on Backbone.js events catalogue, but none of them seems logic (except "sync"). Maybe "reset", but it is just for Collections

Is this a better approach?

weatherModel.fetch({
    success : function() {
        App.mainRegion.show(weatherView);
    }
});

I thought 'sync' was supposed to work like that... but the success callback would work certainly
