This approach ensures that you can close a popover by clicking anywhere on the page. If you click on another clickable entity, it hides all other popovers. The animation:false is required else you will get a jquery .remove error in your console.
$('.clickable').popover({
trigger: 'manual',
animation: false
}).click (evt) ->
$('.clickable').popover('hide')
evt.stopPropagation()
$(this).popover('show')
$('html').on 'click', (evt) ->
$('.clickable').popover('hide')
