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();
});

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
