jQuery autocomplete - adding to underlying local datasource array
<p>In this basic example using jQuery autocomplete:</p>

<pre><code>$("#textboxid").autocomplete(
    {
        source: testdata,
        delay: 100,
        minLength: 1
    });
</code></pre>

<p>where <code>testdata</code> is a local array of data, what is the recommended way to have any changes to the underlying source array, reflect in the autocomplete options?</p>

<p>Currently, if I subsequently add a new item to the <code>testdata</code> array (i.e. after the autocomplete has already been setup on the textbox element), I don't see that new option in the autocomplete list. If I dynamically add a new textbox to the page and set up for autocomplete, it does see the new option. But existing elements do not.</p>
