bootstrap datepicker won't load from javascript

When I load the datepicker through the data-provide="datepicker", it will show up but not in safari. I also need to block out dates, such as the weekend. I was thinking both problems could be solved loading it through javascript and throwing in some config variables but I'm getting an error:

ReferenceError: $ is not defined

I'm thinking it's because maybe the jquery is being loaded in the wrong order, but other functionality is working.

Test site is here: http://ift.tt/1IAc7WZ

Field for datepicker is under "Select your prefered day & time"

Any help would be greatly appreciated!
