weekStart option doesn't working

[nhat-tong]

Hi there,

I would like to display the calendar from Monday to Friday.
In my script, I configured the option weekStart = 1 but it doesn't working (it started always from Sunday).

<script type="text/javascript" charset="utf-8">
		new Kalendae(document.body, {
			months:1,
			mode:'week',
			weekStart: 1,
			direction:'future',
			blackout: function (date) {
				return [1,0,0,0,0,0,1][Kalendae.moment(date).day()]; //blackout weekends
			}
		});
</script>

What can I do?
Thanks in advance,
