title: ExtJs didn't fire select event on ComboBox
body: <p>I have a problem with ExtJs <code>combobox</code>, consider I have a <code>combobox</code> that has 4 items and a callback function in <code>select</code> event on <code>combobox</code>. </p>
  
  <p>When I'm going to set the <code>combobox</code> selected value with <code>setValue()</code>, ExtJs don't fire <code>select</code> event.</p>
  
  <p>How can I fix this problem?</p>
  
  <p>Should I fire this event after <code>setValue()</code> by myself?</p>
