title: Google Analytics Event Tracking doesn't track twice or more
body: <p>I am trying to track an event via Google Analytics but unfortunately it only works for the first time I click the element. When I change the browser it only works the first time again.
  I use this simple code to track:</p>
  
  <p><code>ga('send', 'event', 'footer', category , label, 1);</code></p>
  
  <p><code>category</code> and <code>label</code> are JS variables</p>
  
  <p>Any ideas why this is not working?</p>
