Send user notification every hour with Bot Framework NodeJS - node.js

Question

I am developing a bot that sends users a message every hour on skype. It makes an API call and then sends a message containing the parsed message. I started with the welcomebot sample. I then used the switch statement to fire a setInterval()to send the message activity when the user sends a certain message but the message keeps sending even after I call clearinterval() I set to a different string. How can I make clearInterval() work? Or am I going about it the wrong way?
