JQuery 2.1.3 in Windows Store, need a dialog box

I had an app I was working on using JQuery 1.6. I've upgraded the project to JQuery 2.1.3, for a Windows Store app, and for the most part it's working.

However, I had a dialog call, that would give the user a message and Ok/Cancel buttons. This fails now.

I'm sure I'm just searching the wrong terms. How can I get a simple Ok/Cancel dialog box?
