title: JSTree.js - making attributes retain updated values
body: <p>I am using JSTree.js and am trying to make attributes in LI elements in the UL list, that is using jstree, to retain updates to their values.  </p>
  
  <p>E.g. I have an attribute called data-cmsid that is set to a value when the tree is created.  If I change the attribute of datacmsid using some JQuery then code view shows the value has changed, but that doesn't seem to be the case in the actual js tree.</p>
  
  <p>Does anybody know how to make the js tree retain attribute value changes?  I'm using drag and drop with the tree too - not sure if that affects anything?</p>
