title: Looking for javascript event equivalent to 'onRender'
body: <p>I'd like to add to my <code>&lt;td&gt;</code> element JS event listener that will be triggered when the page is rendered (or loaded) to the DOM and the TD contains its innerHTML value.
  something like:</p>
  
  <pre><code>&lt;script&gt;
  function manipulate(field){
  field.value = field.value+'_done';
  }
  &lt;/script&gt;
  &lt;td onRender=manipulate(this)&gt;Hello World&lt;/td&gt;
  </code></pre>
  
  <p>I can't use <strong>onLoad</strong> because it can be used in <code>&lt;body&gt;</code> only to my understanding
  Is there any way to do it?</p>
