title: famo.us input surface type range min/max attributes
body: <p>I'm trying to set min max attributes for inputSurface of type range, but its not working. The generated input element doesn't have min/max attributes.</p>
  
  <p>My code:</p>
  
  
  
  <pre class="lang-js prettyprint-override"><code>  var moveDown = this.options.flyerSheetHeight + this.options.flyerItemHeight + 2;
  
    var downModifier = new StateModifier({
        transform: Transform.translate(0, moveDown, 0)
      });
  
      var flyerItemGenSurface = new InputSurface({
        size: [this.options.flyerSheetWidth, 5],
        type: 'range',
        min: 1,
        max: 10,
        properties: {
          zIndex: 1,
        }
      });
  
      this.mainNode.add(downModifier).add(flyerItemGenSurface);
  </code></pre>
