How to create a dynamically growing list in SAPUI5?

Hi,

I want to create a growing list in SAPUI5 like this http://help.sap-ag.de/saphelp_uiaddon10/helpdata/en/91/64ba7047b74a25a19baf9c5bb986ae/content.htm

However, I want to hit a url to fetch data every time[10 rows on every load]. My JSON data contains more than 200 rows and I do not want to load everything when the app starts. Can you help me with your code for achieving this?

Thanks

Senthil Kumar
