Change text in JQM Collapsible without including <span>click to collapse contents</span> text

Change text in JQM Collapsible without including <span>click to collapse contents</span> text

I am trying to change the heading text of a collapsible, but no matter what I try, it always includes the span text as well. 

Here is the enhanced HTML:
  1. <div data-role='collapsible' class='...'>
  2.       <h4 class='...'>
  3.             <a href='#' class='...'>
  4.              "Some Text"
  5.              <span class='ui-collapsible-heading-status'> click to collapse contents</span>
  6.              ::after
  7.             </a>
  8.       </h4>
  9. </div>

  
The selectors I have tried to isolate the "Some Text" so far:
  2. $("div [data-role^='collapsible'] a:not(':first-child')")
  3. $("div [data-role^='collapsible'] a:not('span')")
  4. $("div [data-role^='collapsible'] a:not('.ui-collapsible-heading-status')")
  5. $("div [data-role^='collapsible'] a:not('span.ui-collapsible-heading-status')")
Is there a selector that will reference "Some Text" without the span text?

TIA (Omar to the rescue again?)
