Autocomplete funciona, meu problema é com os seletores jquery para campos dinamicos...

<div id="origem">

<div class="row">
  <div class="col col-md-3">
  <div class="input-group">
    
    <input type="text" class="auto form-control" id="autoprod" name="prod[0]" placeholder="Produto...">

     <input type="hidden" id="prodid" name="prodid[0]" value="0">

     <script type="text/javascript">

               
  $(document).ready(function(){

    var i = 0;

    $('#autoprod').eq(i).autocomplete({
        source: function(request, response) {

          $.ajax({
            url:'<?php echo base_url().'Compras/prodList'; ?>',
            type: 'post',
            dataType: 'json',
            data: {
                search: request.term
            },
            success: function(data){
                response(data);
            }

          });
        },
        select: function(event, ui){
          $('#autoprod').eq(i).val(ui.item.label);
          $('#prodid').val(ui.item.value);
          $('#marca').val(ui.item.marc);
          $('#unit').val(ui.item.uni);

          return false;
