title: As a "target" handler toolbar button, the method of the controller?
body: <p><strong>Hello!</strong></p>
  
  <p>I want this handler "handler: onEventControler (???)" removed from view (it do not belong there)</p>
  
  <p>For grid view  set dockedItems this  cod:</p>
  
  <pre><code>        this.dockedItems = [{
          xtype: 'toolbar',
          items: [{
              xtype: 'newstation'
          },{
              id: 'add-persone-btn',
              xtype: 'button',
              itemId: 'add',
              text: 'Add',
              iconCls: 'icon-add',  
              handler: onEventControler(???)
          }, '-', {
              itemId: 'delete',
              text: 'Delete',
              iconCls: 'icon-delete',
              disabled: true,
              handler: function(){
                  var selection = grid.getView().getSelectionModel().getSelection()[0];
                  if (selection) {
                      store.remove(selection);
                  }
              }
          }]
      }]
  </code></pre>
  
  <p>I also tried to implement a <strong>this.control</strong>, but I could not ask for a button selectorQuery.</p>
  
  <p>How do I properly respecting the architecture mvc extJs4?</p>
  
  <p>thank you.</p>
