Droppable to pause till receive value from pop-up

Dear All,
I got a droppable function. Where when I drop it will open a pop-up window and in that once I check one of the checkbox the window will close and then I would like to capture the values and update a particular function. The problem now once the pop-up called the next operation is keep going in the droppable function. How to do like a pause there? Part of my codes is below.

drop: function(event, ui) {
    	
         var sourceID =ui.helper.context.id;
    	
    	tyreInsertID=0;
    	window.open('tyreDetails.php?tyre=' + sourceID, 'TyreDetails','width=500, height=500');
	    return false;
}

// This is the function called from the pop-up once the checkbox is click but is a javascript function not a jquery.

function updateValue(positionID,tyreID,tyreInsertIDPop,tyreCost,val,brand,size,pattern)
  {
	tyreInsertID=tyreInsertIDPop;
	alert("VALUE :"+tyreInsertIDPop+"  "+operationType);
	addRowsRetread("F1L","TEST",val,1,88881);	
  
  }
