Select2: Uncaught Error: Option 'ajax' is not allowed for Select2 when attached to a <select> element.

Even with Select2 4.0.0 we're seeing this error. As per the announcement we're no longer adding the input element.

html :

javascript :
$('.select2').select2({
minimumInputLength:2,
placeholder: $(this).attr('data-placeholder'),
ajax: {.....

Update :
Still works with <input type="hidden" class="select2" />

Is the documentation correct ? or am I missing something ?

p.s: select2 was installed today via bower

Ok.. marking this as resolved.
There was an older version of select2 which was was conflicting here.
Resolved.
