title: Leaflet elevation profiles with multiple GeoJSON features
body: <p>I have a map which loads a GeoJSON containing two features (lines). I would like to use Leaflet Elevation plugin to display an elevation profile for each of those lines. The problem with my code is that when I click a feature, there is no data added to the elevation profile.</p>
  
  <pre><code>var map = L.map('map').setView([44.635, 22.653], 11);
  var osm = L.tileLayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png').addTo(map);
  
  function addData(e) {
      var el = L.control.elevation();
      el.addData(e);
      map.addControl(el);
  }
  
  function onEachFeature(feature, layer) {
      layer.on({
          click: addData
      });
  }
  
  var trails = new L.GeoJSON.AJAX('https://googledrive.com/host/0B55_4P6vMjhITEU4Ym9iVG8yZUU/map.geojson', {
  onEachFeature: onEachFeature
  }).addTo(map);
  </code></pre>
