How can I use Rate Yo jQuery star rating plugin with data attribute?

Question

How can I use Rate Yo jQuery star rating plugin with data attribute?
Is there any way to set a default initial value via HTML attribute?
Is it possible using data-rateyo-score to pass the score value.

For example, If I want to start my score depending on a dynamic value, How can I use callback for it?

My code is same as below:
<div class="rateYo" data-rateyo-score="1"></div>

I try below code:

$('.rateYo').rateYo({
  score: function() {
    return $(this).attr('data-rateyo-score');
  }
});

and this:

$('.rateYo').rateYo({
  score: $(this).attr('data-rateyo-score');
  }
});

But it seems that something is wrong.

Use "data-rateyo-rating='1'" instead "data-rateyo-score='1'"

$(function () {
  $(".rateyo").rateYo().on("rateyo.change", function (e, data) {
    var rating = data.rating;
    $(this).parent().find('.score').text('score :'+ $(this).attr('data-rateyo-score'));
    $(this).parent().find('.result').text('rating :'+ rating);
   });
});
