Sencha touch 2 beta3 - Custom xtype

[subramani]

I am new to sencha touch.
I created a simple code using kitchensink and navigation view with touch 2 beta3.
Currently my app has two screens, contact list and user list. The user list may refer contact list. So I would like to create contact list as a comman class. In the app i would like to call the contact list were ever i want like shown below

{
    xtype: 'contactview'
     items:[
        <!-- When user select an item just specify the call back event -->
    ]
}

is that possible ? I have attached my code. That code may be wrong. Can any one guide me how to do that and how to write a common class code.

Your requirements aren't 100% clear. To have items in your own class then you just use the items config in the config object within the Ext.define call.
