How to Open and Close Angular-UI popovers programmatically

Question

I need to create popovers that gets its content from the server.

So I created the following directive:

.directive('myPopover', [myService, function ($myService) {
        return {
            restrict: 'E',
            transclude: true,
            template: '<a href="" ng-click="wordClicked()" class="highlight" popover-trigger="manual" popover="Adequately good for the circumstances" popover-title="good enough " popover-placement="bottom" ng-transclude></a>',
            link: function (scope, element, attrs) {
                scope.wordClicked = function () {
                    if ( POPUP IS NOT SHOWING ){
                        var message = myService.getMessage({key: element.text()},
                            function () {
                                    console.info("NEED TO SHOW POPOVER WITH "+ message);
                                });
                    }
                    else {
                        console.info("NEED TO CLOSE POPOVER");
                    }
                }
            }
        }
    }]);

And inside getMessage success method I need to make the popover to show. The documentation does not give any indication for that though I found comment made By Luthur here it seems like there is a popover-trigger="manual" option. Could not find a way to trigger it programmatically

Update: I tried to follow Mosho advice but I am having troubles creating a popover with the custom event trigger.

Thanks!

First, if you haven't already looked, here are the sources for tooltips and popovers:

tooltip.js

popover.js

You can add custom triggers. Popovers use the $tooltip provider:

.directive( 'popover', [ '$tooltip', function ( $tooltip ) {
  return $tooltip( 'popover', 'popover', 'click' );
}]);

Where the $tooltip's provider $get method, used to make new tooltip's, is defined here:

 this.$get = [ '$window', '$compile', '$timeout', '$parse', '$document', '$position', '$interpolate', function ( $window, $compile, $timeout, $parse, $document, $position, $interpolate ) {
    return function $tooltip ( type, prefix, defaultTriggerShow ) {...}

The $tooltip provider has this method: (triggerMap is the 3 triggers that are defined in the $tooltip provider out of the box.

   /**
   * This allows you to extend the set of trigger mappings available. E.g.:
   *
   *   $tooltipProvider.setTriggers({'openTrigger': 'closeTrigger'});
   */
  this.setTriggers = function setTriggers ( triggers ) {
    angular.extend( triggerMap, triggers );
  };

You can use it in a config block, like this:

myApp.config(['$tooltipProvider', function ( $tooltipProvider ) {
  $tooltipProvider.setTriggers({'openTrigger': 'closeTrigger'}) ;
}]);

Then, you can create a new popover directive like this:

.directive('myPopover', ['$tooltip', function ( $tooltip ) {
  return $tooltip( 'myPopover', 'myPopover', 'openTrigger' );
}]);

And triggering the popover would then be as simple as element.triggerHandler( 'openTrigger' ) (or closeTrigger) where element is the popover.
