In order to get this sample app to work properly, specifically, to get the ADD BUTTON to work, you'll need to add the following function to the \controllers\index.js file in your FaveBook project:
function addBook() { var addbookview = Alloy.createController("addbook").getView(); addbookview.open(); }
For some reason, this was not added to the code-along instructions for this sample project.
Happy coding!
