Check Change Listener

[Oxii]

What is the right way to handle menu check items events ?
I have this menu:

 {      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                              
      }                      
                }             
          }

Then the functions:

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(???);        
         .          
        .    },

1- Is there anyway to use one listener and gather all different functions in it ?
2- How can I send the current item to goToFunction() as you see in the code ?

The first argument passed to the listener function is the CheckItem instance. You don't need to look it up using Ext.getCmp, you already have it.

In general you should avoid using fixed ids and Ext.getCmp.
