Dojox/app keeping models synchronized with store - model-view-controller

Question

I am currently using dojox/app to create a SPA, and I am starting now to add stores and models. I have been able to create a store from a json object, to create a model from the store, and to bind fields to the model using dojox mvc. However, I have something that I have not yet been able to do: update a 2nd model that is binded to the same store as the 1st one.
I will give an example. I have this store:
win.global.modelApp = {};
modelApp.names = {
identifier: "id",
items: [{
"id": 1,
"First": "John",
"Last": "Doe",
},{
"id": 2,
"First": "John2",
"Last": "Doe",
}]
}
and then I create two models using this store in the config.json file:
"stores": {
"namesStore":{
"type": "dojo/store/Memory",
"params": {
"data": "modelApp.names"
}
}
},
"models": {
"namesXUnused": {
"modelLoader": "dojox/app/utils/mvcModel",
"type": "dojox/mvc/EditStoreRefListController",
"params":{
"store": {"$ref":"#stores.namesStore"}
}
},
"namesXUnused2": {
"modelLoader": "dojox/app/utils/mvcModel",
"type": "dojox/mvc/EditStoreRefListController",
"params":{
"store": {"$ref":"#stores.namesStore"}
}
}
}
Then, in my HTML file, I have a field binded to namesXUnused (property First), and another binded to namesXUnused2 (property First). When I edit the first field, I then have a button that commits these changes to the store. I can see via debugger that the store data has been correctly updated. However, I cannot get the second field to reflect the changes. Is there a way to refresh or recreate the model from the store?
Thank you,

I think you need to set "observable": true, on the store to use an Observable store since you want to have updates to the store be reflected back to the models. There are examples in the dojox/app/tests (and the dojox/mvc/tests) if you have problems, but just adding:
"observable": true, to your namesStore should do it.
"stores": {
"namesStore":{
"type": "dojo/store/Memory",
"observable": true,
"params": {
"data": "modelApp.names"
}
}
},
