searchBuilder plus highCharts - chart not updating after search

Hi,

I've set up my web page to use SearchBuilder and HighCharts plug-in's which are working but after I do a search using the searchBuilder, the chart does not update as expected. I would expect the code below to detect the table draw and update the chart but it is never called, although the datatable updates accordingly.

dtRepotable.on('draw', function () {
    console.log("Redrawing chart")
    repoChart.series[0].setData(chartData(dtRepotable));
});

Any suggestions, please?

Thanks, Chris
