QnA maker Microsoft and custom functions in nodejs

Hy folks, I have some issues with qna maker on azzure portal.

I'm trying to make a custom bot who's responding on user's input.

if(userInput == 'something'){
  foo();
}else{
  AnswerMeToQuestion();
}

I made the QnA on azzure website. Everything works great, until I want to join it with other custom function. Do I need to declare another connector or another bot ? I have no idea what's the next step. https://jsfiddle.net/spzz1o0g/
