when a multiselect is created using enableFiltering : true like this
$('.multiselect').multiselect({
includeSelectAllOption: true,
enableFiltering: true
})
the search option appears and its all OK.

but after a rebuild is made
$("#mySelect").multiselect('rebuild');

the search option disappears...

how can i rebuild the multiselect with enableFiltering: true?
or at least inject this property after the rebuild is made.
