Cannot Get Jquery Call Right For Eternicode Bootstrap Datepicker

I have been trying out the eternicode/bootstrap-datepicker (https://github.com/eternicode/bootstrap-datepicker). I tried out the sandbox (http://eternicode.github.io/bootstrap-date

Solution 1:

OK this was a typo (or more accurately newb lack of jQuery understanding!!)

$('.datepicker.date').datepicker.(

should have been

$('.datepicker.date').datepicker(

IE I stuck in an extra period. (And that cost me at least two hours! D'oh!)
