title: Dynamically fill Sencha Touch picker
body: <p>I'm using Sencha Touch in one of my mobile projects. As one of the components of it I'm using the Picker. I know that the picker values are being got from the "data" attribute which is an array containing object like so:</p>
  
  <pre><code>[{"text":"One","value":1},{"text":"Two","value":2},{"text":"Three","value":3}]
  </code></pre>
  
  <p>However what I need to do is - fill the picker with values from an array which is being generated dynamically from a store. Could anybody help me with this, please?</p>
  
  <p>Thanks.</p>
