Yammer Like Button Not Working… TypeError: yam.helper is undefined-Collection of common programming errors

I am using yammer’s like button. I have tried every browser under the sun. They all have the same funcationality. First page load they will load the JS and the like button perfectly… However after the first page load any subciquent load of the like button throws the below error.

  Error
  TypeError: yam.helper is undefined

code as follows:

  //JS
  yam.connect.actionButton(
    { container: '#like',
        network: 'gsk.com',
        action: 'like'
  });
  //MarkUp
  

Any ideas?
