Solution 1:

In order to get the tooltips to work in the first place, you have to initialize them in your code. Ignoring AngularJS for a second, this is how you would get the tooltips to work in jQuery:

$(document).ready(function(){
    $('[data-toggle=tooltip]').hover(function(){
        // on mouseenter
        $(this).tooltip('show');
    }, function(){
        // on mouseleave
        $(this).tooltip('hide');
    });
});

This will also work in an AngularJS app so long as it's not content rendered by Angular (eg: ng-repeat). In that case, you need to write a directive to handle this. Here's a simple directive that worked for me:

app.directive('tooltip', function(){
    return {
        restrict: 'A',
        link: function(scope, element, attrs){
            element.hover(function(){
                // on mouseenter
                element.tooltip('show');
            }, function(){
                // on mouseleave
                element.tooltip('hide');
            });
        }
    };
});

Then all you have to do is include the "tooltip" attribute on the element you want the tooltip to appear on:

<a href="#0" title="My Tooltip!" data-toggle="tooltip" data-placement="top" tooltip>My Tooltip Link</a>

Hope that helps!

Solution 2:

The best solution I've been able to come up with is to include an "onmouseenter" attribute on your element like this:

<button type="button" class="btn btn-default" 
    data-placement="left"
    title="Tooltip on left"
    onmouseenter="$(this).tooltip('show')">
</button>
