title: dojo 1.8 - Unable to update ComboBox every time there ia a change in select
body: <p>Hi I have a select(3 options) and a ComboBox to be updated with new options each time select is changed. However, I am not able to update or refresh ComboBox each time the select is changed. It only works if the page is refreshed.</p>
  
  <pre><code>meter_Select.on('change', function()
  {
  console.debug("selected -&gt; " + meter_Select.value);
  switch(meter_Select.value)
  {
  case 'testdata1970_05': var memoStore2 =  new Memory({data:response2});
  break;
  case 'testdata1970_10': var memoStore2 =  new Memory({data:response3});
  break;
  case 'testdata2060_03': var memoStore2 =  new Memory({data:response1});
  }
  
  var combx = new ComboBox({
  store: memoStore2,
      searchAttr: "mfg_code"
      }, "node_cardSelect");
      combx.startup();
  </code></pre>
