sencha touch local storage insert ID - html

Question

I have a small problem if you can help me it would be great. I cant insert my own ID to the local storage.
ext.define('EMC.model.ReferenceData', {
extend: 'Ext.data.Model',
config: {
identifier: {
type: 'simple'
},
idProperty: 'Id',
fields: [
{name: 'Id', type: 'string'},
{name: 'Description', type: 'string'},
{name: 'syncChangeVersion', type: 'integer', mapping: 'SysChangeVersion'},
{name: 'TypeEnum', type: 'string'}
]
}
});
this is a model of my project and the store is shown below.
Ext.define("EMC.store.SyncReferenceData", {
extend : "Ext.data.Store",
requires : [ 'Ext.data.proxy.LocalStorage' ],
config : {
model : 'EMC.model.ReferenceData',
storeId : 'referenceStore',
sorters : 'Id',
proxy : {
type : 'localstorage',
id : 'reference_data'
},
autoSync : true,
autoLoad : true
}
});
this is the phrase I created to insert data to the local storage using controller.
var frmModel2 = Ext.create('EMC.model.ReferenceData',{
Id : '13',
Description : 'lole',
syncChangeVersion : 0,
TypeEnum : '199'
});
ReferenceStore.add(frmModel2);
ReferenceStore.sync();
But when I see the local storage it is empty. But If i comment Id : '13' then it will add to the local storage with a id of "ext-record-293".
why cant I inset my own Id to the store?

Try like this..
Ext.define('EMC.model.ReferenceData', {
extend: 'Ext.data.Model',
config: {
dProperty : 'uniqueid', // dummy name(not a field)
clientIdProperty : 'Id',
fields: [
{name: 'Id', type: 'string'},
{name: 'Description', type: 'string'},
{name: 'syncChangeVersion', type: 'integer', mapping: 'SysChangeVersion'},
{name: 'TypeEnum', type: 'string'}
]
}
});
