 The result of this is an alert box that says, "I DID IT!"
 
+By default all triggers are stopped with `preventDefault` and `stopPropagation` methods. But you can manually configure the triggers using hash instead of event name. Example below triggers an event and prevents default browser behaviour using `preventDefault` method.
+```js
+Backbone.Marionette.CompositeView.extend({
+  triggers: {
+    "click .do-something": {
+      event: "something:do:it",
+      preventDefault: true,
+      stopPropagation: false // this param is optional and will default to false
+    }
+  }
+});
+```

 You can also specify the `triggers` as a function that 
 returns a hash of trigger configurations
