title: MVC CheckBox change event
body: <p>I am new to MVC so I think I need to be pointed in the right direction.</p>
  
  <p>I have a boolean in my model which creates a checkbox in my view using:</p>
  
  <pre><code>@Html.EditorFor(model =&gt; model.Adults)
  </code></pre>
  
  <p>I also have a dropdownbox which shows content from a ViewBag. I want to show different ViewBag sets depending on the condition of that checkbox. </p>
  
  <p>I can do it by checking my mode.Adults variable using Razor syntax in my html, but this will only work on my edit page, not on the create page. Also, it will not work when I click on the checkbox (I would need it reloaded with new values in the dropdown list).</p>
  
  <p>I was hoping to avoid posting back to the server using jQuery, and instead do it all client side. However if this is the ONLY way to do it, can someone help on HOW to do it.</p>
