You are assuming list is a jQuery object. It is just a string.

You did not show you add so I cannot see if you use commas or what.

Perhaps you mean this:

 $("#" + newrID).val(list.replace(ID2,""))

My Add is here

var newdID = 'd' + ID;
                  var curr_relID = $("#" + newdID).val();
                  curr_relID = curr_relID.split(",");
                  curr_relID.push(ID2);
                  $("#" + newdID).val(curr_relID.join(","));

Then my code is
 $("#" + newrID).val(list.replace(","+ID2,""));

Or split, loop and delete item then join if array not empty
