Bootstrap tabs tab('show') refuses to work

Good day,

I am creating a page with bootstrap tabs (BS4) in a form.

Now I need to have a forward and a back button form navigation and I want to use BS4's tab('show') functionality.

However even in a proof of concept I fail to get it to work. I wonder what I have done wrong.

I checked if all Id's are set and if everything is matching. So far everything is correct. Console log does not give me any errors or whatsoever.

I hope I am making a simple bug and this is not a bootstrap issue.

Below my proof of concept code :

My functions.js file's contents : 

function activaTab(tab) {
    var tabID = '#' + tab;
    console.log('You just clicked on a function to activate tab : ' + tabID);

    if ($(tabID).length == 0) {
        console.log('But I have to inform you of the misfortunate event that the tab ID you want to pick strangely does not exist');
    }

    $('.nav-tabs a[href="' + tabID + '"]').tab('show'); // Select tab by name
};

My HTML file's contents:

function activaTab(tab) {
    var tabID = '#' + tab;
    console.log('You just clicked on a function to activate tab : ' + tabID);

    if ($(tabID).length == 0) {
        console.log('But I have to inform you of the misfortunate event that the tab ID you want to pick strangely does not exist');
    }

    $('.nav-tabs a[href="' + tabID + '"]').tab('show'); // Select tab by name
};

    </div>
</div>
</body>
</html>

edit:

A very tired mind caused this..

$('.nav-tabs a[href="' + tabID + '"]').tab('show'); // Select tab by name

to be changed in :

$('.nav-pills a[href="' + tabID + '"]').tab('show'); // Select tab by name

In your activaTab() method, you are calling tab('show') on an element having the class name nav-tabs, but the element you wish to display has the class nav-pills. The correct call should be:

$('.nav-pills a[href="' + tabID + '"]').tab('show'); // Select tab by name
