angularjs - Create Hoverable popover using angular-ui-bootstrap

Question

I have the following code for creating a popover in my template file:

<span class="icon-globe visibility" 
      id="visibilityFor{{post.metaData.assetId}}" 
      popover="{{post.visibilityListStr}}" 
      popover-placement="right" 
      popover-trigger="mouseenter" 
      popover-popup-delay="50" 
      visibility>
</span>

I have a few clickable links on the popover. But the problem is I'm not able to hover on the popover created. I referred to the link http://jsfiddle.net/xZxkq/ and tried to create a directive viz. 'visibility' for this purpose.

Here is the code:

myAppModule.directive("visibility", function ($timeout,$rootScope) {
  return {

    controller: function ($scope, $element) {
        $scope.attachEvents = function (element) {
            $('.popover').on('mouseenter', function () {
                $rootScope.insidePopover = true;
            });
            $('.popover').on('mouseleave', function () {
                $rootScope.insidePopover = false;
                $(element).popover('hide');
            });
        }
    },
    link: function (scope, element, attrs) {
        $rootScope.insidePopover = false;

        element.bind('mouseenter', function (e) {
            $timeout(function () {
                if (!$rootScope.insidePopover) {
                    element.popover('show');
                    attachEvents(element);
                }
            }, 200);
        });

        element.bind('mouseout', function (e) {
            $timeout(function () {
                if (!$rootScope.insidePopover) {
                    element.popover('show');
                    attachEvents(element);
                }
            }, 200);
        });

    }
  }
});

But I get an exception for 'element.popover' since it is undefined. Please point as to what I'm doing wrong and how can I show/hide the angular ui popover from the directive. I am using angular ui bootstrap JS file.

I have solved it in a very cleaned way and thought to share it:

.popover is being created not as a child of the uib-popover so the idea is to wrap uib-popover with a parent and to control show&hide on hovering the parent.

.popover and uib-popover are children of this parent so just left to set popover-trigger=none and you have what you are wishing for.

I created a plunk example:

<span ng-init="popoverOpened=false" ng-mouseover="popoverOpened=true" ng-mouseleave="popoverOpened=false">
    <button class="btn btn-default" uib-popover-html="htmlPopover" 
            popover-trigger="none" popover-placement="bottom-left" popover-is-open="popoverOpened" >
       <span>hover me</span>
    </button>
</span>

enjoy.
