Dynamically add a class to Bootstrap's 'popover' container

Question

I\'ve thoroughly searched through both StackOverflow and Google, but come up empty. So apologies in advance if this has been asked & resolved already.

The best solution for this problem is to extend the popover and built your own version of Popover. Below is the code and it's based on bootstrap version 3.3.7

        (function($){
            var PopoverEx = function(element, options){
                this.init('popover', element, options);
            }

                PopoverEx.prototype = $.extend({}, $.fn.popover.Constructor.prototype, {

                    constructor: PopoverEx,
                    tip: function(){
                        if(!this.$tip){
                            this.$tip = $(this.options.template);
                            if(this.options.modifier) this.$tip.addClass(this.options.modifier);
                        }
                        return this.$tip; 
                    }       
                });

            $.fn.popoverex = function(option){
               return this.each(function () {
                var $this   = $(this)
                var data    = $this.data('bs.popover')
                var options = typeof option == 'object' && option

                if (!data && /destroy|hide/.test(option)) return
                if (!data) $this.data('bs.popover', (data = new PopoverEx(this, options)))
                if (typeof option == 'string') data[option]()
              })
            }
        })(window.jQuery);
