-### 4. Create and Configure your own event adapter <a id="config-adapter"></a>
+### 4. Create your listener <a id="create-listener"></a>
+You need to create your listener/subscriber class in order to load your events data in the calendar.
+
+```yml
+// service.yml
+services:
+   app_bundle.service.listener:
+        class: AppBundle\Listener\LoadDataListener
+	tags:
+   		- { name: 'kernel.event_listener', event: 'fullcalendar.set_data', method: loadData }
+
+```
+
+This listener is called when the event 'fullcalendar.set_data' is launched, for this reason you will need add this in your service.yml.
