title: Polymer element blur event
body: <p>I am trying to see what is easy to do with polymer and am having a hard time getting the seemingly simplest events to fire.  </p>
  
  <pre><code>&lt;polymer-element name="field" attributes=" type name value"&gt;
    &lt;template&gt;
      &lt;label&gt;{{name}}
        &lt;input  type={{type}} name={{name}} value={{value}}&gt;
      &lt;/label&gt;
    &lt;/template&gt;
    &lt;script&gt;
      Polymer('field', {
        onblur: function () {
          console.log('blurred');
        }
      })
    &lt;/script&gt;
  &lt;/polymer-element&gt;
  </code></pre>
  
  <p>I have created this element and want to do something on blur does anyone know what I am missing or where in the docs I should be looking?</p>
