title: Keep calling a function on mouseDown in ember
body: <p>I need to keep calling a function on <code>mousedown</code> and I have following code:</p>
  
  <pre><code>&lt;button id="zoomin" type="button" {{action "zoomIn" on="mouseDown" target="view" }} class="btn"&gt;
      &lt;i class="icon-zoom-in"&gt;&lt;/i&gt;
  &lt;/button&gt;
  </code></pre>
  
  <p>But it is only called when mouse is down and I want it to be called repeatedly until mouse is up.</p>
  
  <p>Is there any solution other than <code>timer</code>?</p>
