title: dijit.form.Combobox show label Instead of value
body: <p>I've a <code>dijit.form.Combobox</code> field which uses a <code>ItemFileReadStore</code> to pull Its data.
  Teh ItemFileReadStore has two attribute per Item <code>value</code> which will be used for form submission , generally Unique Integers and <code>label</code> which is Human Understandable String.
  In ComboBox HTML I've done <code>searchAttr="value" labelAttr="label"</code>
  When the ComboBox Shows the list it uses teh label Attribute.
  But When the User selects one of the Item it shows the value of that Item.</p>
  
  <p>What I want is , The value Attribute will Still be used for Form Submission. But the User will always see the label in the combobox Control.</p>

  <p>e.g. I Want to Show The Label for value 3 (Admin) instead of 3</p>
