ExtJS 4 store and manage record - json

Question

I have a question about extjs 4.
Below is my storeMsg
var storeMsg = this.getMessageStore();
storeMsg.load({
scope: this,
autoLoad: true,
params:{
read_conditions: Ext.JSON.encode({
"employee_rid": '7976',
"year" : '2013', //etos
"kind_holiday_rid" : '1',
"request_days" : '5'
})
},
callback: function(records, operation, success) {
// do something after the load finishes
console.log(records[0].get('remain'));
console.log(records[0].get('messages'));
}
});
and i take a json response like as
{"total":1,"success":true,"data":[{"status":"true","messages":"\u03a3\u03c9\u03c3\u03c4\u03cc \u03b1\u03af\u03c4\u03b7\u03bc\u03b1 \u03ac\u03b4\u03b5\u03b9\u03b1\u03c2","remain":"25"}]}
I want to take the field status from json (ex true) outside from storeMsg.load();
For example
var vstatus = Ext.StoreMgr.lookup(storeMsg).data.items[0].data.status
but i take message this vstatus is undefined
I have changed my variable (vstatus) of code :
var vstatus = Ext.StoreMgr.lookup(storeMsg).getProxy().getReader();
and I am taking and object like as
className "Ext.data.reader.Json"
and it has some attributes. An attribute is
jsonData
data
remain 25
status true
message "Is correct"
total 1
success true
and I give in
var vstatus = Ext.StoreMgr.lookup(storeMsg).getProxy().getReader().jsonData;
and I take this message (undefined).
Do you have any idea how take the value from jsonData.data.status = true;
tnx
and the fully code about store , proxy and reader is below
Ext.define('MHR.store.Message',{
extend : 'Ext.data.Store',
model : 'MHR.model.Message',
storeId : 'Message',
autoLoad : true,
proxy : {
type: 'ajax',
api: {
read : 'php/crud.php?action=check'
},
actionMethods: {
read : 'POST',
},
reader: {
type: 'json',
root: 'data',
rootProperty: 'data',
successProperty: 'success',
messageProperty: 'message'
},
extraParams : {
'read_conditions': ''
}
}
});

try with:
storeMsg.each(function(record) {
var status = record.get('status');
});
