title: knockoutjs: prevent event bubbling for elements with no handler
body: <p>It seems like the binding <code>&lt;event&gt;Bubble: false</code> only works when there's <a href="http://knockoutjs.com/documentation/event-binding.html" rel="noreferrer">a defined event handler</a> (<em>see Note 4</em>) for <code>&lt;event&gt;</code>.</p>
  
  <p>Here's an example <a href="http://jsfiddle.net/stvnmntjy/stjFM/" rel="noreferrer">fiddle</a>.</p>
  
  <p>For elements having native handlers for certain events (e.g. click: <code>&lt;textarea&gt;</code>, <code>&lt;a&gt;</code>, <code>&lt;select&gt;</code>, etc.), where the native handler suffices, I would expect setting the binding, e.g., <code>clickBubble: false</code> on them, without having to bind a "bogus" handler, to work.</p>
  
  <p>I guess my question is, is there another knockout way to achieve this without extra bindings?</p>
