I would like to recommend these two blogs when you want discover more: Andrey Markeev: Callouts (popovers) в SharePoint 2013 Preview (in Russian) Alex Boev: a three part series: 1. Custom Callouts in the SharePoint 2013 Metro UI: Part 1: Basics 2. Custom Callouts in the SharePoint 2013 Metro UI, Part 2: Actions 3. Custom Callouts in the SharePoint 2013 Metro UI, Part 3: CalloutManager To get introduced with callouts in SharePoint 2013, you can run this code (from Andrey Markeev’s blog):

It is not a rocket science to pass objects from child window (popup) to main window. The problem I encountered today was IE and passing complex objects. So it is just an IE issue as far as I know. The problem occurs when you pass some object (not a simple String or Number) to main window:
