title: Modifying Ajax post request data using dojo/notify api
body: <p>I am trying to attach a Form data variable to Ajax Post Request using DOJO/NOTIFY. For example: there is a form which sends an item <strong>a = 10</strong> to the server. <strong>Using dojo/notify (send)</strong> I attach another variable <strong>b=5</strong> with the ajax post request <strong>but the problem is that it does not work and only a=10 is sent to server</strong>. Following is my code:</p>
  
  <pre><code>require(["dojo/request", "dojo/request/notify"], function (Request, Notify) {
  
      //Called before sending Ajax Request
      Notify("send", function (request) {
          dojo.byId("status").innerHTML = "Sending Ajax Request";
          /*
            At this point I want to add another form data item before 
            it is sent to Server.Example b = 5. The following is the 
            way to do it but It does not seem to work:
          */
  
          request.options.data += "&amp;b=5";
          //I also tries the following but it also not working:
          //request.options.data.b = "5";     
      });
  
      Request.post("http://jsfiddle.net/",{
          data:{a:10}
      });
  });
  </code></pre>
