title: Extjs 4.1 Check Change Listener
body: <p>What is the right way to handle menu check items  events ?</p>
  
  <p>I have this menu:</p>
  
  <pre><code> {
        xtype: 'button',
        id: 'types_btn',
        autoWidth: true,
        text: 'Types',
        menu: {
                xtype: 'menu',
                frame: true,
                id: 'types_menue',
  
                items: [
                         {
                           xtype: 'menucheckitem',
                           id: 'f_type',
                           text: 'first',
                           listeners: {
                              checkchange: {
                                      fn: me.onFirstButtoncheckchange,
                                      scope: me
                                      }
                                        }
                         },
                         {
                          xtype: 'menucheckitem',
                          id: 's_type',
                      text: 'second',
                           listeners: {
                              checkchange: {
                                      fn: me.onSecondButtoncheckchange,
                                      scope: me
                                      }
                                        }
                         }
  </code></pre>
  
  <p>Then the functions:</p>
  
  <pre><code>onFirstButtoncheckchange: function(menucheckitem, checked, options) {
  
      var t = Ext.getCmp('f_type');
                 if (t.checked)
                     goToFunction(???);
                   .
                   .
      },
   onSecondButtoncheckchange: function(menucheckitem, checked, options) {
  
      var t = Ext.getCmp('s_type');
                 if (t.checked)
                     goToFunction(???);
                   .
                   .
      },
  </code></pre>
  
  <p>1- Is there anyway to use one listener and gather all different functions in it ?</p>
  
  <p>2- How can I send the current item to goToFunction() as you see in the code ?</p>
