title: Vuejs JSX onTouchStart is not recognized
body: <p>I'm trying to use JSX with Vuejs and currently I try to do this</p>
  
  <pre><code>export default {
    methods: {
      handleClick: function (e) {
        console.log('clicking: ', e)
      },
      handleTouchStart: function (e) {
        console.log('touching: ', e)
      }
    },
    render (h) {
      return (
        &lt;div
          className="slider"
          onTouchStart={(e) =&gt; this.handleTouchStart(e)}
          onClick={(e) =&gt; this.handleClick(e)}&gt;
          &lt;h1&gt; Hey there &lt;/h1&gt;
        &lt;/div&gt;
      )
    }
  }
  </code></pre>
  
  <p>The <code>handleTouchStart</code> function is not called, but we can still see <code>handleClick</code> is called while clicking the element. I'm not sure how many Synthetic events are supported in Vue JSX syntax ?</p>
  
  <p>Do we need any other library to let Vue know about <code>touch</code> events ?</p>
