title: Event 'after setAt' in google maps api
body: <p>I have some confusing problem here,</p>
  
  <p>I tried to capture the polyline.getPath lat &amp; lng with this code :</p>
  
  <pre><code>google.maps.event.addListener(Polyline.getPath() , "set_at" , function(tmpposisi, urutan){
  
  
    function index(tmpposisi, urutan){
  
      for (var i = 0; i &lt; this.getLength(); i++)
      { 
        urutan = i;
  
      }
  
      function cek(tmpposisi){
        urutan = this.getAt(tmpposisi);
      }
  
    }
  
    console.log(tmpposisi,urutan.toUrlValue(4), data[ Number( tmpposisi) ] );
  
  });
  </code></pre>
  
  <p>but, when I tried to drag the polyline path, the console return the "previous lat &amp; lng" instead of the newest lat &amp; lng. I think the 'getAt' fired at the same time (or before) with 'set_at' fired as mentioned in google maps API documentation. </p>
  
  <p>my question is, how can I get the newest lat &amp; lng from Polyline path ? which is the one after event 'setAt' Triggered ?? or if it's not possible, how can I achieve my purpose with different approach ??</p>
  
  <p>thanks !</p>
