i newbie extjs 4.1, developed small app wherein have master , slave concept i.e basis on master's ajax success have fire slave's ajax request, if slave fails master should fail , vice versa. please find below snipnet of code

controller.js

    ext.define('basel3.controller.contacts', {         extend: 'ext.app.controller',         stores:['...my store goes here...'],         models:['...my models goes here...'],         views: ['...my views goes here...'],         refs:[{             references goes here         }],         init: function(){               this.control({                 ....         })         },         save: function() {               this.getrulesstore().save();               this.getruledetailsstore().save();         }     }
