javascript - Date Range Picker how to fire an event on entering a date

Question

I'm using Dan Grossman's daterangepicker.

http://www.dangrossman.info/2012/08/20/a-date-range-picker-for-twitter-bootstrap/

Which is initialised in my web page, and now I'm trying to write the javascript that will be implemented once the date is entered by the user. However I have run into difficulty getting the daterangepicker to fire an event.

The code I'm using is

$('#dateRange').on('changeDate', function(ev){
    alert(ev);
});

And here is the code that initialises the daterangepicker

$('#dateRange').daterangepicker({
    ranges: {
        'Today': [moment(), moment()],
        'Yesterday': [moment().subtract('days', 1), moment().subtract('days', 1)],
        'Last 7 Days': [moment().subtract('days', 6), moment()],
        'Last 30 Days': [moment().subtract('days', 29), moment()],
        'This Month': [moment().startOf('month'), moment().endOf('month')],
        'Last Month': [moment().subtract('month', 1).startOf('month'), moment().subtract('month', 1).endOf('month')]
    },
    startDate: moment().subtract('days', 29),
    endDate: moment()
},
function(start, end) {
    $('#dateRange span').html(start.format('MMMM D, YYYY') + ' - ' + end.format('MMMM D, YYYY'));
});

I've tried lots of different ways to listen for the event like on.('blur') or on.('enter') but nothing is firing the event for me.

From daterangepicker.com:

$('#daterange').on('apply.daterangepicker', function(ev, picker) {
    alert ('hello');
});
