It is possible to send some extra data to jsonstore?

Bassicaly json data looks like this:

I need send something more, eg:

A reader has a createAccessor method that you pass in the property you want to use. This method will return a method that you pass in the raw data from the response and when you execute that method it will return the value.

this.createAccessor('title')(rawData) === 'Documents'

I usually cache the function the createAccessor on the store so that I'm not creating the function over and over

I'm not sure I understand

I try something like this:

var store = new Ext.data, JsonStore ({
id: 'ID',
totalProperty: 'totalCount'
root: 'items',
url: 'getData.php'
fields: [...]
listeners: {
load: function (store, records, opts) {
var fnTitle = store.reader.createAccessor('title');

And then what?
I have some function fnTitle()
But any call of this method fires exception
