title: updated server, now need to show latest update in ListView
body: <p>I have an app which shows a list of the funds from this api in a listView via asynctask. I want create a button in which they will be able to add a new fund by doing a POST command. How can I get this latest entry to show in the listView ?
  Should I recall my asynctask? That seems redundant. Could there be a better way?</p>
