As it is now, the dialog is dismiss as soon as the Android back button is pressed, which is wrong for my use case. How can I handle it? 

There is still a surrounding key handler in DefaultDialogWrapper.qml, because we wouldn’t want it to be too easy to break the default behavior: most dialogs should be dismissed when you hit the back button.  So content which is merely added to the Dialog’s default property does not get the chance to break it.

Instead you can override the Dialog’s contentItem, which is also another way to get rid of the buttons.
