Make compound path in Adobe Illustrator by script

There are some compoundPathItems in myfile.ai

How can i run "Object > Compound Path > Make" or send "ctrl+8" from jsx? At line with comment ERROR HERE i get error message "A new object cannot be created at the specified location".

#target illustrator

if (app.documents.length > 0) {
  var idoc = app.activeDocument; 
  var cp = idoc.compoundPathItems.add();
  var allPaths = activeDocument.pathItems;
  //Select objects
  for(var i = 0;i < allPaths.length;i++){
  allPaths.selected = true;
  }

  var selection = app.activeDocument.selection;
  for (var i=0; i<selection.length; i++) {
  selection.move (cp, ElementPlacement.PLACEATEND); // move selected path inside the compound path ERROR HERE 
  selection.evenodd = true; // necessary to determine "insideness" or to make holes.  
  }

  alert(selection);
