How to make a button in rqt with jsk?

edit

I have done some research on how to make a button in rqt and I came across this option from jsk. I have downloaded the jsk package from github. Now that I have the plugin installed how do I actually get the service button example to run in rqt? Could someone walk me threw the steps I need to do to get the downloaded example to appear in an rqt window. Thank you very much to anyone who can help I am using ubunto 16.04 and ros kinetic
