Bot - Override Dialog behaviours

gistfile1.txt

// See: http://www.pveller.com/smarter-conversations-part-2-open-dialogs/#Trigger-Actions
// You can define your own dialog’s behaviors by overwriting begin, replyReceived, and even recognize on your dialogs:
bot.dialog('custom', Object.assign(new builder.Dialog(), {
    begin: (session) => {
        session.send('I am built custom');
    },
    replyReceived: (session) => {
        session.endDialog();
    }
}));
