In your case the choice of custom formatter seems me wrong. The problem is that the custom formatter will be called not only during the initial grid load, but can be called later. So It seems to me the usage of jsonmap the better:

{name: 'name', width: 250, editable: true,
    jsonmap: function (obj) {
        var prop, name = obj.name, assignment, resource, values = [], i, n;
        for (prop in name) {
            if (name.hasOwnProperty(prop)) {
                assignment = name[prop];
                if ($.isArray(assignment)) {
                    for (i = 0, n = assignment.length; i < n; i++) {
                        resource = assignment[i];
                        values.push(resource.employeeName + '[' +
                            resource.assignPercent + ']');
                    }
                }
            }
        }
        return values.join(', ');
    }}

You have to define jsonReader too:

jsonReader: {
    repeatitems: false,
    root: "list"
}

Additionally it's important to fill TreeGrid specific properties. You can fill the part of the properties inside of beforeProcessing callback. On the example below I filled all the TreeGrid specific properties in beforeProcessing:

beforeProcessing: function (data) {
    var i, list = data.list, n, item;
    if ($.isArray(list)) {
        for (i = 0, n = list.length; i < n; i++) {
            item = list[i];
            if (typeof item.level === "undefined") { item.level = 0; }
            if (typeof item.parent === "undefined") { item.parent = null; }
            if (typeof item.isLeaf === "undefined") { item.isLeaf = false; }
            if (typeof item.expanded === "undefined") { item.expanded = false; }
            if (typeof item.loaded === "undefined") { item.loaded = true; }
        }
    }
}

UPDATED: I changed in the demo the local cell editing to the local inline editing because cell editing don't support work with TreeGrid.
