Sending proactive messages to ms teams from azure

I've already deployed the bot to azure, when connecting to the ms team channel in azure, i'm able to ping the bot and receive messages which is good. I've also added a proactive messaging in the bot where a message will be triggered every one minute in the channel. [Connecting to MS Teams][1] Its working in the emulator, however its not working in webchat and MS teams: The notifier controller is not being triggered. Could you please help me on that? I've uploaded the code in GITHUB: [login to view URL]
