$(form)
    .bootstrapValidator({
        ...
    })
    .on('success.form.bv', function(e) {
        // Called when the form is valid
        
        var $form = $(e.target);
        if ($form.data('remote') && $.rails !== undefined) {
            e.preventDefault();
        }
    });

Reference:

• success.form.bv event

If you don't, your form will be submitted two times.
