RadGridView SortMemberPath does not update dynamically?

When setting the RadGridView.SortMemberPath = "SomeMemberName", when the model object raises an INotifyPropertyChanged for SomeMemberName, the grid doesn't seem to re-sort.

Is this the expected behavior?

I'm trying to display dynamically updated data in the grid, where I want to sort the column on some arbitrary member property in the model (e.g. display CPU history in a column and sort on the 10 second average).

How can I make sure that the grid automatically re-sorts when a member in the model is updated?

Thanks,
Alex

Grouping By Date

The following code produces a bar chart showing average request amount grouped by year and type:

List<RequestData> produceList = new List<RequestData>();

produceList.Add(new RequestData("2", 132, DateTime.Today, "Cash Grants"));

produceList.Add(new RequestData("1", 145, DateTime.Today.AddYears(1), "Cash Grants"));

produceList.Add(new RequestData("3", 149, DateTime.Today.AddYears(1).AddDays(1), "Cash Grants"));

produceList.Add(new RequestData("4", 187, DateTime.Today, "Cash Grants"));

produceList.Add(new RequestData("5", 186, DateTime.Today.AddYears(1), "Matching Gifts"));

produceList.Add(new RequestData("6", 131, DateTime.Today, "Dinners & Events"));

produceList.Add(new RequestData("7", 173, DateTime.Today.AddYears(1), "Dinners & Events"));

produceList.Add(new RequestData("8", 172, DateTime.Today, "Matching Gifts"));

produceList.Add(new RequestData("9", 140, DateTime.Today.AddYears(1), "Cash Grants"));

produceList.Add(new RequestData("10", 129, DateTime.Today, "Dinners & Events"));

produceList.Add(new RequestData("11", 158, DateTime.Today, "Matching Gifts"));

produceList.Add(new RequestData("12", 164, DateTime.Today.AddYears(1).AddDays(1), "Dinners & Events"));

SeriesMapping seriesMapping = new SeriesMapping();

seriesMapping.SeriesDefinition = new HorizontalBarSeriesDefinition();

seriesMapping.GroupingSettings.GroupDescriptors.Add(new ChartGroupDescriptor("Type"));

seriesMapping.GroupingSettings.GroupDescriptors.Add(new ChartYearGroupDescriptor("RequestDate"));

seriesMapping.ItemMappings.Add(new ItemMapping("RequestAmount", DataPointMember.YValue, ChartAggregateFunction.Sum));

seriesMapping.ItemMappings.Add(new ItemMapping("RequestDate", DataPointMember.XCategory));

radChart.SeriesMappings.Add(seriesMapping);

radChart.ItemsSource = produceList;

radChart.DefaultView.ChartArea.AxisX.DefaultLabelFormat = "yyyy";

However, if I change the order of the data so that item 12 comes directly after item 3 like so:
