Can't get stars to show in simple review system

I'm currently trying to implement a simple star review system to my application and I got it working for the most part. But the issue Is I can't get the the review stars to show for the average review of a store. Anyone mind helping me understand what is broken?

stores/show.html.erb:

<div class="star-rating" data-score= <%= @avg_review %> ></div>
<em><%= "#{@reviews.length} reviews" %></em>

This is included at the bottom of the view: 

<script>
$('.star-rating').raty({
  path: '/assets/',
  readOnly: true,
  score: function() {
        return $(this).attr('data-score');
}
});
</script>

stores_controller.rb: 

def show
@reviews = Review.where(store_id: @store.id).order("created_at DESC")

if @review.blank?
  @avg_review = 0
else
  @avg_review = @reviews.average(:rating).round(2)
end
end

Thank you a head of time.

Put in your model store:  

def average_rating
    reviews.count == 0 ? 0 : reviews.average(:rating).round(2)
end

(If no star = 0, otherwise we average the notes)

In your view: 

<span id="average_rating"></span>

With the script:

<script>
$('#average_rating').raty({
    path: '/assets',
    readOnly: true,
    score: <%= @store.average_rating %>
});
</script>
