Hide the DatePicker on button click

[Oscar Morrison]

I am using a calendar icon in a input box to open the bootstrap datepicker (1.4). 

I want to be able to simply close the datepicker when re-clicking this icon again. 

I have tried to set a flag in the datepicker show and hide event, and then check if the datepicker is open to change the behavior of the button. 

But I have found that the hide event fires before the on click event and the datepicker hides then immediately re-shows. 

Thanks
