It's a bit tricky because ng-bind-html will simply insert plain old html and not bother compiling it (so any directives in the html will not be processed by angular.

The trick is finding a way to compile whenever the template changes. For example, you could create a directive that does this. It would look something like:

.directive('compileTemplate', function($compile, $parse){
    return {
        link: function(scope, element, attr){
            var parsed = $parse(attr.ngBindHtml);
            function getStringValue() { return (parsed(scope) || '').toString(); }

            //Recompile if the template changes
            scope.$watch(getStringValue, function() {
                $compile(element, null, -9999)(scope);  //The -9999 makes it skip directives so that we do not recompile ourselves
            });
        }         
    }
});

You can then use it like this:

<p ng-bind-html="myHTML" compile-template></p>
