Store HasMany doesn't sync

[izak18]

Hi, i have a problem saving data in a model type HasMany, this is my code:

Model:

Ext.regModel('pedidoModel',{    idProperty: 'id',
    fields: [
        {name: 'id', type: 'int'},
        {name: 'ClaseDocumento', type: 'string'},
        {name: 'Referencia', type: 'string'},
        {name: 'CodigoCliente', type: 'string'}
    ],
    associations: [
        {type: 'hasMany', model: 'interlocutoresModel', name: 'interlocutores'}
    ],
    
    proxy:
    {
        type: 'localstorage',
        id: 'pedidoStore'
    }
});


Ext.regModel ('interlocutoresModel', {
    fields: [
        {name: 'pedidoModel_id', type: 'int'},
        {name: 'Funcion', type: 'string' },
        {name: 'Codigo', type: 'string'}
    ],
    
    associations: [
        {type: 'belongsTo', model: 'pedidoModel'}
    ],
 
    proxy: {
        type: 'localstorage',
        id: 'interlocutores'
    }    
});

Code:

var currentDoc = interlocutoresView.store.last();

var interStore = currentDoc.interlocutores();

var Funcion = panel1.getValues().Funcion;

var Codigo = panel1.getValues().Codigo;

var inter1 = Ext.ModelMgr.create(
    {'Funcion':Funcion,'Codigo':Codigo},
    'interlocutoresModel'
);

panel1.load(inter1);
var currentInter = panel1.getRecord();

interStore.add(currentInter);
interStore.sync();
console.log(interStore.data.items);

I can get the item saved like I see in the console, but when I refresh the page, the data is gone.
What I can do? Is anything wrong in my code?

Thanks in advance.

Do you see the sync request fire off in the network tab?
