title: passing multiple arguments to addCallBackElement Google Script
body: <p>Is there any way to add multiple arguments to an addCallBackElement() function in Google Scripts? I want to send information about what the user typed into a given text box, as well as an integer. Can I send both of these? If not, is there any way I can see what the user typed into a textbox without actually having a handler function? Thanks!</p>
  
  <p>For example:</p>
  
  <pre><code>var count = 0
  var handler = app.createServerHandler('myClickHandler').addCallbackElement(textBox, count);
  </code></pre>
