title: JAWS not reading updated aria-label
body: <p>We are using a custom angular table which includes sorting functionality as well.</p>
  
  <p>When the user sorts column1 we are setting <code>aria-label</code> for column1 as:
  "Click to sort column1 in ascending order". </p>
  
  <p>If the user clicks again on same header we are changing the same aria-label to "Click to sort column1 in descending order". </p>
  
  <p>But it is observed that the updated <code>aria-label</code> is not detected by JAWS narrator.</p>
  
  <p>How we can resolve this issue where JAWS can read an updated <code>aria-label</code> or is there any alternative for this ?</p>
  
  <p>Thanks</p>
