For a ListView adapter, how is getView() called?
Firstly, do I need to call getView() manually or does it get called automatically? No, it get called automatically. If so, when is it actually called?

Custom adapter notifyDataSetChanged not working
You're creating a new adapter in change(), but you aren't assigning it to the ListView.

Then you can call adapter.notifyDataSetChanged() to refresh the list.

Trying to use jsonp with ember-data, and unable to use Ember App's store.createRecord in custom adapter
This parsing of the response seems more like a job for the RESTSerializer than the RESTAdapter(though you will still need the adapter if you need to set the dataType/url) Not 100% sure, but it looks like your reponse is an array that doesn't have the correct key as stated in the documenation? If this is the case, you'd want to create a serializer for events like this App.EventsSeria
