title: setInterval in IONIC 3
body: <p>I would like to run a function in every 1 second. After searching, I found <code>setInterval</code> but it doesn't work for me.</p>
  
  <pre><code>setInterval(function(){ 
     this.myfuntion();
  
  }, 1000);
  </code></pre>
  
  <p>I also tried <code>this.myfuntion</code> but it doesn't work too.</p>
