Method in options object initialization is only called once per page load
<p>I have the following code</p>

<pre><code>$(".datePicker").datepicker({
    dateFormat: 'dd/mm/yy',
    autoSize: true,
    changeYear: true,
    changeMonth: true,
    yearRange: getYearRange()
});
</code></pre>

<p>The getYearRange function is only called once although there are many .datePickers.
To be clear, the getYearRange function will be called with the $(this) parameter.</p>
