Javascript only works on the same page [closed]

I have a problem with some Javascript routines that only work on the same page, they stop working when I put them in another file in which I have other Javascript routines that work normally, the first function shows me a tooltip in some submit buttons, the other is a simple function that changes the lower case to uppercase, this way I have them on the page:

<script>
    $(document).ready(function(){
        $('[data-toggle="tooltip"]').tooltip(); 
         });

    function mayus(e) {
        e.value = e.value.toUpperCase();
    }
</script> 

When I put them in a file p utilitarios.js does not recognize them. I include this file on the page as follows:

<script src="views/js/jquery.js"></script>
<script src="views/js/bootstrap.min.js"></script>
<script src="views/js/utilitarios.js"></script>

What should I do to make it work properly ??.
