Selecting radio input

Selecting radio input

In the html code below how can i select the last radio input element tried
$('#div1 > :radio :last-child')
$('#div1 > :radio input:last-child') both don't work.
Any ideas, without necessarily adding a class to the specific radio input.

NB: the number of input elements are dynamic, I just want to select the last radio input element

<div id='div1'>
      <input type='text' />
      <input type='radio' />
      <input type='radio' />
      <input type='text' />
</div>
