You can also build your own extended triggers. This will apply to both Tooltip and Popover.

First extend the Tooltip triggers as follows:

// define additional triggers on Tooltip and Popover
app.config(['$tooltipProvider', function($tooltipProvider){
    $tooltipProvider.setTriggers({
        'show': 'hide'
    });
}]);

Then define the trigger on the HTML tag like this:

And now you can call hide and show from JavaScript, this is a show in 3 seconds.

$("#RegisterHelp").trigger('show');
//Close the info again
$timeout(function () {
    $("#RegisterHelp").trigger('hide');
}, 3000);
