how can i pop-up a jquery datepicker(keith-wood plugin ) on click of a div tag?

I am using jquery date picker with keith-wood plugin for multiple selection and multiple months.

i have a division tag that displays the date and besides i have one more division tag that holds an image.
when i am clicking on the image division tag i need to show the calender.

i tried     
$a('#dvDate').datepick({
            multiSelect: 90, monthsToShow: 3, monthsToStep: 3,
            prevText: 'Prev months', nextText: 'Next months'
        });

        $a('#dvDateImage').click(function () { $a('#hidDate').datepick("show"); });

with hidden field but it is not working and this is not the one that i exactly want. if i can avoid hidden field and only with div tag then it would have been far better.
