Autocomplete field reset via JS

[Mackski]

I'm using a page reference autocomplete field in a template as a "lookup" then populating other fields via ajax call.
I want to reset the autocomplete on success, i've tried a few things but the value still persists..

What i've tried:

$('#Inputfield_search).val('') // no effect
$('#Inputfield_search).data('selectedlabel',''); // no effect

I guess last resort would be to trigger the (X) on the autocomplete input.

Is there an easier way to reset this field type via JS?
