Click Event on particular barchart stick

First of all i want to say a lot of thanks to this oxyplot tools.
I wants to perform some task on clicking particular barchart(means its stick drawn) . Is it possible to make certain click event on clicking those barchart stick.If possible please suggest.
thanks in advance.

The MouseDown event should be available on the BarSeries. Note that we consider removing the events when the new PlotController is implemented: https://oxyplot.codeplex.com/workitem/10132

Thanks for your kind suggestion.
i tried your suggestion, as event fire i have just displayed a message it works on clicking the whole chart area but i wants only the event on clicking the bar chart only, but the message is displaying on clicking whole chart area .
Doing on this:

plotModel1.MouseDown += (s, e) =>

        {
            if (e.ChangedButton != OxyMouseButton.Left)
            {
                return;
            }                               
            e.Handled = false;
            MessageDialog msgDialog = new MessageDialog("Welcome", "Alert!");
            msgDialog.ShowAsync();                
        };
