How can I change highcharts events after the chart has been initialized

Question

How can I change highcharts events after the chart has been initialized?

<div id='report'></div>

var chart = $('#container').highcharts({
        chart: {
        },

        xAxis: {
        },

        plotOptions: {
            series: {
                point: {
                    events: {
                        mouseOver: function() {
                            $reporting.html('inner x: '+ this.x +', y: '+ this.y);
                        }
                    }
                },
                events: {
                    mouseOut: function() {                        
                        $reporting.empty();
                    }
                }
            }
        },

        tooltip: {
            enabled: false
        },

        series: [{
            data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]        
        }]
    });

chart.options.plotOptions.series.point.events.mouseOver = function() {
$('#report').html('outer x: ' + this.x + ', y: ' + this.y);
}

I want to override the mouseOver event as above, but it seems not effected. I'll be very appriciated for anyone could help.

It's not supported to update plotOptions in real time. jsFiddle.

You can update one-series options in that way:

chart.series[0].update({
  point: {
    events: {
      mouseOver: function() {
        $('#report').html('outer x: ' + this.x + ', y: ' + this.y);
      }
    }
  } 
});
