add event to x-axis labels of bar highchart

Question

I am trying to retrieve the text of a label on the char x-axis by clicking on it. I am using bar chart and the code is the following:

var chart = new Highcharts.Chart({
    chart: {
        type: 'column',
        backgroundColor: '#eaedf1',
        zoomType: 'x',
        renderTo: 'container'
    },
    plotOptions: {
        series: {
            cursor: 'pointer',
            pointWidth: 10,
            point: {
                events: {
                    click: function (event) {
                        console.log(event.point.name + " " + this.y);
                    }
                }
            }
        }
    },
    title: {
        text: 'Total Flow Types'
    },
    xAxis: {
        type: 'category',
        labels: {
            rotation: -90
        }

    },
    yAxis: {
        min: 0,
        title: {
            text: 'millions'
        }
    },
    legend: {
        enabled: false
    },
    series: [{
        name: 'Flow Types'
    }]
});

Then by clicking on a button the chart gets populated using ajax which works fine. By checking the dom of the chart I saw that each of the labels is text /text. They are part of g/ element with a class highcharts-axis-labels highcharts-xaxis-labels. So I've tried retrieving the values using jquery like:

$('body').on('click', 'g.highcharts-axis-labels.highcharts-xaxis-labels text',   function () {
    console.log($(this).text());
});

or just

$('body').on('click', 'text',   function () {
    console.log($(this).text());
});

This all is part of the document.ready function. Unfortunately none of these retrieves the text of a x-axis label?

there's nothing to post really. If you copy and paste my chart code and provide some example data you will see what it produces — george

Instead of:

$('body').on('click', 'g.highcharts-axis-labels.highcharts-xaxis-labels text', function () {
    console.log($(this).text());
});

Use this:

$('.highcharts-xaxis-labels text').on('click', function () {
    console.log($(this).text());
});

You should not connect classes highcharts-axis-labels and highcharts-xaxis-labels with a dot. And also the class highcharts-xaxis-labels is enough to add the event on. Here's the fiddle: http://jsfiddle.net/8sxLr5j8/
