Creating sorted tree in DOJO 1.6? - dojo

Question

I new to learn dojo and trying to learn by it using samples code.
Using dojo 1.6
With help of sample codes , I created a tree
now i want to apply sorting on root and also on child.
With the help of this sample code , i changed the code
Output is not sorted n but the root folder has changed their position and child is deleted.
Plz help me to resolve this.
My code :
dojo.require("dojo.data.ItemFileWriteStore");
dojo.require("dojo.data.ItemFileReadStore");
dojo.require("dijit.tree.ForestStoreModel");
dojo.require("dijit.Tree");
var data = [ { id: 1, name: "answerTypeLabel", type:'scenario', children:[{_reference: 2}]},
{ id: 2, name: "acceptRequestLabel", type:'paragraph', data: "acceptRequestLabel"},
{ id: 3, name: "rejectRequestLabel", type:'scenario', children:[{_reference: 5},{_reference: 6}]},
{ id: 4, name: "MoreInformationLabel", type:'scenario', children:[{_reference: 7},{_reference: 8}]},
{ id: 5, name: "rejectRequestStatusLabel", type:'paragraph', data: "rejectRequestStatusLabel"},
{ id: 6, name: "rejectRequestNotCoveredLabel", type:'paragraph', data: "rejectRequestNotCoveredLabel" },
{ id: 7, name: "MoreInformationDocumentLabel", type:'paragraph', data: "MoreInformationDocumentLabel"},
{ id: 8, name: "MoreInformationDataLabel", type:'paragraph', data: "MoreInformationDataLabel"}
];
dojo.addOnLoad(function() {
var sortableStore = new dojo.data.ItemFileReadStore({
data: {
identifier: 'id',
label: 'name',
items: data
}
});
var model = new dijit.tree.ForestStoreModel({
rootLabel: 'Names',
store: new dojo.data.ItemFileWriteStore({
data: {
identifier: 'id',
items: [],
label: 'name'
}
}) // blank itemsstore
})
var tree = new dijit.Tree({
model: model,
updateItems: function(items) {
var self = this;
console.log('pre', this.model.root.children);
dojo.forEach(items, function(newItem) {
console.log('add', newItem);
try {
self.model.store.newItem({
id: sortableStore.getValue(newItem, 'id'),
name: sortableStore.getValue(newItem, 'name'),
type: sortableStore.getValue(newItem, 'type'),
data: sortableStore.getValue(newItem, 'data'),
});
} catch (e) {
console.log(e);
}
});
console.log('post', this.model.root.children);
console.log("children: ", this.rootNode.getChildren());
},
});
tree.placeAt(dojo.body());
sortableStore.fetch({
query: {
type:'scenario'
},
sort: [{
attribute: "name"}],
onComplete: function(items) {
console.log(items, 'sorted');
tree.updateItems(items);
}
})
});

The 'Names' origins from you setting 'rootLabel'.
Btw, fiddles have revisions and is simply a paste-bin like feature :)
You need to use the tree model pasteItem to insert referenced items (the 'children' property of each 'newItem').
Otherwise, there's another approach, if you get rid of the '_reference' structure of your data. See: http://jsfiddle.net/GHFdA/1/
