Cannot include jQuery Table Sort

We are using Ember with Semantic-UI. We are trying to get a sortable table (http://ift.tt/2ouFpYe).

We installed the kylefox addon with npm install jquery-tablesort

our .hbs file has the following included:

<script src="http://ift.tt/J5OMPW"></script>
<script src="jquery.tablesort.js"></script> 
<script>  
$(document).ready(function() {
     $('table').tablesort();
});
</script>

But I get the following in the console:

jquery.js:3869 Uncaught TypeError: $(...).tablesort is not a function

Is there anything we forgot to include?
