Remove Record and the Add Record doesn't work

[izak18]

Hi guys, I'm here again with a problem, I don't know what could be wrong.
I have a record saved, then I want to remove that record and add a new one but only "remove" it works, adding the new record doesn't, this is the code:

var inter1 = Ext.ModelMgr.create({id: 1, Funcion: 'AG', PedidoId: currentDoc, Codigo: Codigo},'interlocutoresModel');

var currentInter = interStore.getAt(0);
if(!currentInter){
    interStore.add(inter1);
    interStore.sync();
    console.log("Add");
}
else{
    if (interStore.findRecord('id', currentInter.data.id)) {
        interStore.remove(currentInter);
        interStore.sync();
        console.log("Remove");
    }
    interStore.add(inter1);
    console.log("Update");
    interStore.sync();
}

Hope you can help me.
Thanks a lot.

Forget it, I found how to do it in this post:

But still, I dont know why I can't remove and add a record like you can see in the code.
Thanks anyway.
