jquery.steps.js is loaded way after your initialize-steps.js

<script src="/files/js/views/person/initialize-steps.js"></script>
....
<script src="/files/bower_components/jquery.steps/js/jquery.steps.js"></script>
You need to load initialize-steps.js after it

<script src="/files/bower_components/jquery.steps/js/jquery.steps.js"></script>
<script src="/files/js/views/person/initialize-steps.js"></script>
