Question

I created a simple tree based on a TreeStoreModel which is backed by ItemFileWriteStore.
I tried updating my tree by deleting and adding items to the store as below, but could not.

dojo.require("dojo.data.ItemFileWriteStore");
dojo.require("dijit.Tree");
dojo.addOnLoad(function () {
    var tmpData = [{
            "name" : "Dell",
            "type" : "business",
            "businessid" : "1",
            "projectid" : "1",
            "submenu" : [{
                    "name" : "OTP",
                    "type" : "product",
                    "productid" : "100"
                }
            ]
        }
    ];

    var tmpData1 = [{
            "name" : "Lenovo",
            "type" : "business",
            "businessid" : "1",
            "projectid" : "1",
            "submenu" : [{
                    "name" : "OTP",
                    "type" : "product",
                    "productid" : "100"
                }
            ]
        }
    ];
    var store = new dojo.data.ItemFileWriteStore({
            data : {
                label : 'name',
                items : tmpData
            }
        });

    var treeModel = new dijit.tree.TreeStoreModel({
            store : store,
            query : {
                type : 'business'
            },
            childrenAttrs : ["submenu"]

        });

    var divTestTree = dojo.create("div", null, dojo.body(), "first");
    var mytree = new dijit.Tree({
            model : treeModel
        },
            divTestTree);
    /* Tree is created at this point */

    /* Delete the item from the store,  for some reason tempData is being reset*/
    store.deleteItem(tmpData[0]); 
    /* save */
    store.save();
    /* Tree shows up no more at this point */

    /* Try adding new item to the store */
    store.newItem(tmpData1[0]);
    /* save */
    store.save();
    /*nothing happens! */   
});

I followed the lead from here, I must be missing something very trivial here. Please help.
