MessageListener not working in JS

JavaScript
1

After subscribing to the particular tag/channelName, when i publish the message, message listener is not working. Can you please help me to make this work? I only have message listener issue in javaScript not in android.

        channel = Backendless.Messaging.subscribe( channelName );
        channel.addMessageListener( onMessage )

try to add an error handler to check if there are any errors from the server

   channel = Backendless.Messaging.subscribe( channelName );
   channel.addMessageListener( onMessage, onError ) 

function onError(error){
  console.log('error:', error) 
}
