Insert partial/component at dynamic location

I created a blog where I've got a {{downloads}} component showing the downloads which belong to a post. Currently I render the downloads below {{{post.content}}}.

I'd like to have a special string withing post.content like [postDownloads] and render {{downloads}} there.

Is this somehow possible or are there other approaches to solve this problem?

I put together an easy example illustrating one of the use-cases I'm trying to solve: http://ift.tt/1LZhwyY

App = Ember.Application.create();

App.IndexRoute = Ember.Route.extend({
  model: function() {
    return {
      title: "cool post title", 
      content: "<p>Lorem ipsum</p>[postDownloads]<p>coool stuff</p>",
      downloads: [ { src: "http://ift.tt/1y86efX", name: "cool stuff"},
                   { src: "http://ift.tt/1LZhwz0", name: "cooler stuff"}]};
    }
  }
);

Here's the HTML:

<script type="text/x-handlebars">
  <h2>My Blog example</h2>
  {{outlet}}
</script>

<script type="text/x-handlebars" id="components/down-loads">
  <h3>Downloads</h3>
  {{#each download in downloads}}
    <p><a {{bind-attr href=download.src}}>{{download.name}}</a></p>
  {{/each}} 
</script>

<script type="text/x-handlebars" data-template-name="index">
  {{#with model as post}}
    <h3>{{post.title}}</h3>
    <div>{{{post.content}}}</div>
    {{down-loads downloads=post.downloads}}
  {{/with}}
</script>
