dynamic content parent div

I need to change this parent to position : absolute but I cant target it.

Any one know how to target this parent div?

function reward(draggedItemOrig,originSize)

{

  var numItems = $(draggedItemOrig).length

  if (numItems == 1)

  {

  var rewardObj = myComp.getStage().createChildSymbol("reward", "Stage");

  $(rewardObj.element).parent().css({position:'absolute'});

  $(rewardObj.element).css

  ({

  left: originSize[2].left,

  top: originSize[2].top

  });

  };

};
