In this chapter, let's focus on functionalities we have not implemented yet. Do not worry. The complete implementation is available within the source code distributed with this book.
We created all the views for our application. In the base ViewController, we created the handlers for the Add and Edit buttons, and both call the createDialog method, which we are going to develop now.

createDialog: function(record){
var me = this,
view = me.getView(), //#1
glyphs = Packt.util.Glyphs;
me.isEdit = !!record; //#2
me.dialog = view.add(...
