Add value to extjs textarea from store - extjs

Question

I want to get data from mongo data base and add it to an extjs text area.
Everything is ready, my mongo data base returns a list of user email addresses that I want to add to the extjs text area.
I use this code:
var index = Ext.StoreMgr.lookup("writeup.store.Employee").findExact('name',name);
var rec = Ext.StoreMgr.lookup("writeup.store.Employee").getAt(index);
alert(rec.data.name);
But I get this error:
TypeError: Ext.StoreMgr.lookup(...) is undefined
And this is my store
Ext.define('writeup.store.Employee', {
extend: 'Ext.data.Store',
model: 'writeup.model.Employee',
autoLoad: true,
proxy: {
type: 'ajax',
actionMethods: {
read : 'POST'
},
api: {
read : 'user/view.action'
},
reader: {
type: 'json',
root: 'data',
successProperty: 'success'
},
writer: {
type: 'json',
writeAllFields: true,
encode: false,
root: 'employee'
},
listeners: {
exception: function(proxy, response, operation){
Ext.MessageBox.show({
title: 'REMOTE EXCEPTION',
msg: operation.getError(),
icon: Ext.MessageBox.ERROR,
buttons: Ext.Msg.OK
});
}
}
}
});

try this
Load this code into your controller
var store_name = Ext.create('Ext.data.Store', {
model: 'model name'
});
store_name.load();
store_name.each(function(record){
for(var i=0;i<record.data.yourlocalstorageid.length;i++){
var index = record.data.yourlocalstorageid[i].name;
}
}
