can display nested json noram model, there model association needed?

please help...ur appreciated..thanks in advance

change proxy setting in store follows. removed 'rootproperty' , add 'record'

proxy: { type: 'ajax', method:'post', url: 'resources/data/fullproperty.json', //url: apiurl+'propertylist.ashx?switch=getpip&reoid=', reader: {     type: 'json',     record: 'items' } 

}
