AngularJS Informer Service

I am using Twitter Bootstrap for the user interface in my webapp. Partially its component Alert . I want to write a simple angular service to wrap a Bootstrap Alert message in order to be able to inform users from any angular world. Like this:

Informer.inform("message", "ERROR"); // will result in alerting with `alert-error` class
Informer.inform("message", "INFO"); // will result in alerting with `alert-info` class

My idea is to add a template to the end <body>:

<div class="alert {{alertClass}} fade in informer" id="informer">
    <button type="button" class="close" data-dismiss="alert">×</button>
    <div class="valignCenterWrapper">
        <div class="valignCenter" id="informerMessage">
            {{message}}
        </div>
    </div>
</div>

Something like that:

grfx.factory("Informer", function() {
    return {
        inform : function(message, type) {
            // Here be dragons. How can I compile/append the template.

            $("#inform").alert();
        }
    };
});

, : angular, jQuery? ? , DOM. : - . / . ($compile, $parse, $document) temlate - ?

: . JS-, getServiece("Informer").inform("", "")?

2: , :

grfx.factory("Informer", function($compile, $rootScope) {
    return {
        inform : function(message, type) {
            var scope = $rootScope.$new();

            scope.message = message;
            scope.type = type;

            $(document.body).append($compile("<div class='alert {{type}} fade in informer' id='informer'><button type='button' class='close' data-dismiss='alert'>×</button><div class='valignCenterWrapper'><div class='valignCenter' id='informerMessage'>{{message}}</div></div></div>")(scope));
        }
    };
});

. , angular :

angular.element(document).injector().get("Informer").inform("Message", "alert-error");

{{message}} . .
