Stop Ember helper rendering inside div

I have an Ember helper which is literally defined as this:

<span class="glyphicon glyphicon-info-sign" data-toggle="tooltip" data-placement="right" data-title="{{text}}"></span>

It's used to render a Bootstrap tooltip. It renders the following HTML:

<div id="ember572" class="ember-view">
    <span class="glyphicon glyphicon-info-sign" data-toggle="tooltip" data-placement="right" data-title="<script id='metamorph-35-start' type='text/x-placeholder'></script>When a project is archived, no new items can be created in it.<script id='metamorph-35-end' type='text/x-placeholder'></script>" data-original-title="" title="" aria-describedby="tooltip416856">
    </span>
</div>

How can I stop the helper rendering the containing div?
