title: Call click event on last clicked row in YUI datatable
body: <p>I have a YUI datatable and I have a function which is invoked when I click on a row:</p>
  <pre><code>...
  YAHOO.keycoes.myDatatable = myDatatable;
  ...
  myDatatable.subscribe(&quot;rowClickEvent&quot;, oneventclickrow);
  var oneventclickrow = function( args ) {
      ...
  }
  </code></pre>
  <p>I'd like to invoke the function subscribed to <code>rowClickEvent</code> on the row which is currently highlighted in the datatable (the row which was clicked for the last time).</p>
  <p>I've tried to do something like this:</p>
  <pre><code>YAHOO.keycoes.myDatatable.getSelectedRows()[0].rowClickEvent()
  </code></pre>
  <p>but <code>getSelectedRows()</code> doesn't return any row. How can I get the highlighted row in the datatable and then call the function associated with <code>rowClickEvent</code>?</p>
