title: Heroku does not update
body: <p>I'm using Heroku but it seems like that it does not update my code everytime I push it to the master.</p>
  
  <pre><code>$ git add .
  $ git commit -am "make it better"
  $ git push heroku master
  </code></pre>
  
  <p>But after I do this nothing happens.... The output after I push it to the master:</p>

  <p>The strange thing is that somehow I managed to deploy it but don't know how I really did it. ALso when I look at when I deployed the last one was a time ago.
  Thanks in advance!</p>
