title: how to add onchange event to "form" in dojo?
body: <p>I have form something as shown below and it contains various validation text box and filter select. 
  Html:</p>
  
  <pre><code>&lt;form dojoType="dijit.form.Form" id="Form2" action="" method=""&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>And i am trying to connect a form for an onchange event to an entire form but it is not working i.e. if i change some value in filter select or validation text box the event shown below is not triggering?</p>
  
  <p>can any one please help me in this regard? </p>
  
  <pre><code>var handle= dojo.connect(dijit.byId("Form2").domNode,'onchange',function()
  {
      console.log("I am inside the form");
      dojo.disconnect(handle);
  });
  </code></pre>
