title: Pick event not triggered for select field picker,while importing sencha-touch/base scss
body: <p>I am having one select field and want to handle select field picker events manually. Following  code for selectfield :</p>
  
  <pre><code>{
            xtype: 'selectfield',  
            label: 'Choose one',  
            name:'abcd',  
            usePicker:true,  
            options: [  
                {text: 'First Option',  value: 'first'},  
                {text: 'Second Option', value: 'second'},  
                {text: 'Third Option',  value: 'third'}     
  
      ],     
      defaultPhonePickerConfig: {  
          hideOnMaskTap: true,  
          listeners: {  
              change: function(ths, val) {
                 console.log('change event called');
              },
              pick: function(ths, The, slot) {
                console.log('pick event called');
                  PICKER_CONFIG = null;
                  if (PICKER_CONFIG != true) {
                      if (The[slot.getName()] != undefined &amp;&amp; The[slot.getName()] != null &amp;&amp; The[slot.getName()] != "") {
                       //   Ext.getCmp('contractList').setValue(The[slot.getName()]);
                          ths.fireEvent('change', ths, The);
                          ths.hide();
                      }
                  }
              },
              cancel: function() {
                  console.log('cancel called');
                  PICKER_CONFIG = true;
              },
              show:function(){
                console.log('show called');  
              }
          }
      },
  </code></pre>
  
  <p><strong>pick</strong> is not getting called because i am using base css . </p>
  
  <p>Here is my app.scss  </p>
  
  <pre><code>@import 'sencha-touch/base';
  </code></pre>
  
  <p>But its working if i am using <strong>sencha-touch default and default/all</strong> css
  like: </p>
  
  <pre><code>@import 'sencha-touch/default';
  @import 'sencha-touch/default/all;
  </code></pre>
  
  <p>but, i <strong>don't want</strong> to use it<br>
  Is there  any way to get that <strong>pick</strong> by using <strong>sencha-touch/base css</strong>.    </p>
