viewmodel

ext.define('myapp.view.sample.samplemodel', { extend: 'ext.app.viewmodel', alias: 'viewmodel.sample', stores: {     sample: {        // storeid: 'sample', //doesn't work if uncomment     fields: [ 'name' ],         data: [             { name: 'lisa' },             { name: 'bart' },             { name: 'homer',}         ]     } } }); 

you need bind store (which need properties taken viewmodel) , use correct "binding" notation http://www.sencha.com/forum/showthread.php?284474-viewmodel-stores-help

xtype: 'grid', bind: {     store: '{sample}' // curly braces if referencing viewmodel }, columns: [ ... ] 

you using extjs 5, correct? mention because 1 of tags 'extjs4' , viewmodels not introduced until extjs 5.
