title: Jquery Autocomplete display names and send Id
body: <p>How can I change my jQuery autocomplete to use an Id instead of my values?
  I would like to display the list of names but send a search using the Id value. Now it is working properly with the names but I think it will be more effective if it tries to find a unique value as an ID.</p>
  
  <pre><code>$.getJSON('Dashboard/CompaniesWithId', function (data) {
    $.each(data, function (i, item) {
      sellers[i] = item.Name;
      sellersID[i] = item.Id;
    });
  }).error(function () {
    console.log("error loading seller to the autocomplete");
  });
  
  $("#searchSeller").autocomplete({
    messages: {
      noResults: 'No sellers with this name',        
    },
    minLength: 2,
    delay: 500,
    source: sellers,
  });
  </code></pre>
