How do you run multiple routes off of one route controller using iron-router?

Background:

I am making a blog using meteor and iron-router. I want to use a single controller for several different "category pages," which filter a list a blog articles in the yield region.

The Problem:

The article list does not get rerendered when the URL changes. I.e. the article list is not reactive. Interestingly, if I navigate back to the home page, the correct article list shows up.

The Question:

How do I make that article list change when I change between different routes on the category route controller?

Some example code:

Please note that the code for this whole project is available here.

Here is my Route Controller:

CategoryController = RouteController.extend({
    action: function(){
        this.render();
    },
    template: 'category',
    data: function(){
        return {category: this.params.category};
    }
});

CategoryController.helpers({
    articles: function(){
        return Articles.find({category: this.params.category});
    }
});

And here is the template it is rendering:

<template name='category'>
    <div class="container">
        <h2>{{category}}:</h2>
        <ul>
            {{#each articles}}
                <li>
                {{#linkTo route="article.show"}}
                    {{title}}
                {{/linkTo}} 
                </li>
            {{/each}}
        </ul>
    </div>
</template>
