Microsoft Bot Framework, LUIS, take action when the message is not intended

Question

I started learning the Microsoft Bot Framework recently, so I started making Chatbot, and I guess I'm wrong

I am doing chatbot this way:

-> I get a user message
-> send to LUIS
-> get intent and entity
-> select my answer and send it.

this is normal, but get the following situation:

USER: I want to change my email address. → target: ChangeInfo objects: email / value: email

CHATBOT: Please tell me your new email address. → target: noIntent objects: noEntities

USER: [e-mail] → intent: IDon'tKnow: email / value: [e-mail]

I take this situation when the USER sends his email, I send to the LUI, but the letter has no intention, just has the essence, but the letter can be used in many different situations. My question is: how does My bot know the context of the conversation in order to understand that this letter is intended to change the email, and not to send an email or update this message or another.

my gitHub code is here , its ugly code, I know, but I only do this to understand the scope of the bot, after I make this code more beautiful

Answer 2

step, . step, . , . , , .

var data = {step: "asked_email"};
var msg = builder.Message(session).addEntity(data).text("Your message.");
session.send(msg);

LUIS , onBeginDialog:

intents.onBegin(function (session, args, next) {
  if (session.message.step !== "email") {
    next();
  } else {
    //Do something else and not go to LUIS.
    session.endDialog();
  }
});
