Integrate Qr code with sencha touch

[koolll]

I need to implement a qr code to my sencha touch project. Here is the tutorial that I used to follow.http://simonmacdonald.blogspot.com/2...-phonegap.html
I follow the tutorial and the phonegap plugins is working very well in my phone. But nw I got a question. Hw can I customise the layout and implement the plugin to my sencha touch project?
For example when i click member profile button a bar code scanner will appear.
Here is my code.

Ext.define('bluebutton.view.BlueButton.MemberPopUp', {

extend: 'Ext.Panel',xtype: 'memberpopup',requires: [    'Ext.form.Panel',    'Ext.form.FieldSet',    'Ext.field.Text',     'bluebutton.view.BlueButton.MemberDetail'],config: {    items: [                 {                     docked: 'top',                     xtype: 'titlebar',                     items: [                         {                             xtype: 'button',                             text: 'Member Profile'                         },                          {                              xtype: 'button',                              text: 'Transaction History'                          }                      ]                 },                 {                    html : '<div align="center"> <img src="/bluebutton/resources/images/user2.png" alt="Smiley face" height="150" width="150" border="5"> </div>'                 }             ] }
