Ionic realty sample

I Just tried to setup and run the ionic realty app at the following link
"http://coenraets.org/blog/2016/01/ionicrealty-new-ionic-2-sample-application/"

But I get a blank page

Can someone confirm if everything is OK with the code at “https://github.com/ccoenraets/ionic2-realty

What can I do to get more help to fix my code.

Thanks in advance.

Do you see any errors in your developer console (ctrl+shift+j) ?
