ExtJS: checkbox click or keyup event
<p>Now I can handle <code>change</code> event of a <code>checkbox</code> in my <code>controller</code>. I do it like so:</p>

<pre><code>"[itemId=TestCheckbox]": {
   change: this.updateCheckbox
}
</code></pre>

<p>What I do not like about this, is that this event fires even when the state of the checkbox is changed programmatically - when, for example, the value is bound at the first time. All this results in unnecessary server requests:</p>

<ol>
<li>First request gets data from the server and binds the value to the checkbox</li>
<li>Change event is fired and another server request is done</li>
</ol>

<p>I do not like this. I want something like keyup event, or check event, so that I could trigger server request, only when the state of the checkbox is changed by hand and not programmatically.</p>
