extjs - Sencha Touch Ext.picker setData not working correctly -


I'm trying to explain why I can not update the Sina Touch Picker data field The end of) using the setData method I created an array called slots data where I defined my data, the data looks properly: 

  {text: '50 KB / s', value : 50}, {text} '100 KB / s', value: 100}, {text: '200 kb / s', value: 200}, {text: '300 KB / s', value: 300} Code>  
     
  1.  
     When I tried to set up the data Using the Data Card (slots data); No error is displayed, but the picker does not display any data.  
  2.  
     When I tried to update the data like this: 
      slot: [
     {
     name: 'picker_slot1', title: 'slot 1' , 
     data: [slotdata] 
    } 
    ]  This does not work There is no error in the console Picker is empty.   
  3.  
     The only way I can update this syntax is by using:  
      slots: [
     
     
     Name: 'picker_slot1', title: 'slot 1', 
     data: slots data}}]     
     use method # 1 Would someone like me be able to update my picker data while doing this issue? Any help would be appreciated.  
     This code is:  
      my function: function () {var data = this.getData (); Var slotsdata = []; Var PickerData = Data DiesesPluget (','); (Var i = 0; i & lt; picker.data.length; i ++) {slotsdata.push ({text: picardata [i], value: pickcardata [i]})} var picker = Ext.create (' Ext.Picker ', {Slots: [{name:' picker_slot1 ', title:' slot 1 ', data: slotsdata}]}); // it does not work // picasar.secdata (eslotsdata);   
    }   
     
     
     using  setSlots ()  The type of picker class:  
      picker.setSlots ({name: 'limit_speed', title: 'speed', data: [[text: '50 KB / s' , Value: 50}, {text: '100 KB / s', value: 100}]});
