title: How to enable a disabled button by clicking on another button?
body: <p>I have two buttons:</p>
  
  <pre><code>&lt;button onclick=initialize() id="1" data-role="button" data-mini="true" data-corners="false" data-theme="b"&gt;Show My Position&lt;/button&gt;
  &lt;button onclick=calcRoute() id="2" data-role="button" data-mini="true" data-corners="false" data-theme="b"&gt;Evacuate !&lt;/button&gt;
  </code></pre>
  
  <p>I want to have the second button disabled by default, and have it enabled if clicking on the first button. How do I accomplish this?</p>
