Drupal nested json not working in Sencha touch - extjs

Question

My json format
Ext.data.JsonP.callback3({"nodes":[
{"node":{"title":"Dane Sample Name - Owner/Stylist/Daymaker","field_headshot":"","body":"Born and raised in Carencro, La., Dane knew from a young age that he wanted to become a successful hairdresser. \n","nothing":""}},
{"node":{"title":"Rahul - Owner/Stylist/Daymaker","field_headshot":"","body":"Since 1995 Jeanne has enjoyed helping people to feel and look beautiful.\n","nothing":""}}]})
Models
Ext.define('SampleApp.model.Drupal', {
extend: 'Ext.data.Model',
uses: [
'SampleApp.model.Drupal2'
],
config: {
fields : [
'node'
],
},
hasMany: {
model: 'Drupal2',
name : 'node',
associationKey: 'node' ,
}
});
Ext.define('SampleApp.model.Drupal2', {
extend: 'Ext.data.Model',
config: {
fields: [
'title','body'
]}
});
Store
Ext.define('SampleApp.store.DrupalStore', {
extend: 'Ext.data.Store',
requires: [
'SampleApp.model.Drupal2'],
config: {
autoLoad : true,
model: 'SampleApp.model.Drupal2',
proxy: {
type: 'jsonp',
url: 'data/data.json',
reader: {
type: 'json',
rootProperty: 'nodes.node'
}
}
}
});
The above is the nested json from drupal view and I am trying to use those 2 models and store to load list in my view.I am trying to add list of titles from node but List is not loading in the view.If I give root property as nodes then it is loading all the data but not mapping to node.Please help me on where I am going wrong.

Changed my Model, it is not using associations.Here is the Model that worked for me
Ext.define('SampleApp.model.Drupal', {
extend: 'Ext.data.Model',
config: {
fields: [
{
name: 'title',
mapping: 'node.title', // mapping worked
},
{
name: 'field_headshot',
mapping : 'node.field_headshot',
},
{
name: 'body',
mapping : 'node.body',
}
],
}
});
