containers process help

[coder...@gmail.com]

hi

i am following the tutorial from http://dev.lshift.net/james/wireit/wireit/guide.html

till now working fine i am held now for writing process for container. in examples containers code is for just display not doing any process with input values.

like 

modules: [

  {

     "name": "FormContainer",

"category": "form",

     "container": {

  "xtype": "WireIt.FormContainer",

  "title": "WireIt.FormContainer demo",    

  "icon": "../../assets/application_edit.png",

  "collapsible": true,

  "fields": [ 

  {"type": "select", "label": "Title", "name": "title", "selectValues": ["Mr","Mrs","Mme"] },

  {"type": "string", "label": "Firstname", "name": "firstname", "required": true } , 

  {"type": "string", "label": "Lastname", "name": "lastname", "value":"Dupont"}, 

  {"type":"email", "label": "Email", "name": "email", "required": true, "wirable": true }, 

  {"type":"boolean", "label": "Happy to be there ?", "name": "happy" }, 

  {"type":"url", "label": "Website", "name":"website", "size": 25}

  ],

  "legend": "Tell us about yourself..."

  }

  }

      ]

in this example container code just display the container not doing any process with values

i need to know if i have container with two integer inputs fields and one output 

input 1 = 40 

input 2 = 40 

and output = 40 + 40

how can i write container with process  like this
