// TODO: - Couldn't find a good equivalent to gtk_dialog_new_with_buttons
//         in InteractiveDialogClicked
//       - Check how to handle response type. Can we make the button to have
//         the binding to the cancel signal automagicly like in 
//         gtk_dialog_new_with_buttons or should we just use the if ?
