Extjs Combo Autocomplete - ValueNotFountText

[Oxii]

I am using this technique to accomplish an auto-complete feature for a combo boxhttp://cdn.sencha.com/ext-4.1.1a-gpl...um-search.html , it returns name and type of a car, sometimes the type is unknown so nothing returns, I would like it to be "No Data" so I used this

valueNotFoundText: 'No Data'

but didn't work

xtype: 'combo',
store: s,
hideTrigger:true,
typeAhead: false,
id: 'search',
queryMode: 'remote',
queryParam: 'query',
displayField: 'name',//+'type',
valueField: 'name',//+'type',
//valueNotFoundText: 'No Data', 
,listConfig: {         
       loadingText: ' Loading...',         
       getInnerTpl: function() {      
   return  '{name}'+'<br>'+'<p><font size="1">{type}'+':type</font></p>';      
          } ,  
 }   ,  listeners: {
