Mongodb - Update multiple array element inside JSON array

I have an collection doc like .

{'_id':1,
             'name':'Root',
             'taskId':1,
             'parentId':"",
             'path':[1],
             'tasks':[  {"taskId":3,parentId:1,name:'A',status:'Created'},
                        {"taskId":4,parentId:1,name:'D',status:'Created'},
                        {"taskId":5,parentId:4,name:'B',status:'Created'},
                        {'type':'project' , 'proRef':2},
                        {"taskId":6,parentId:3,name:'E',status:'Started'},
                        {"taskId":7,parentId:6,name:'C',status:'Stopped'}]

            }

Now I want to update multiple array element field ‘status’ to ‘Deleted’ which is inside JSON .Let us assume for taskId 3,4 I need to update status to Deleted . I have tried this query with $in with query($) but it is updating very first element is $in array only. In below query only taskId with 3 is getting updated not 4.

db.projectPlan.update({"_id": 1,'tasks.taskId': {$in :[3,4]}} , {$set: {'tasks.$.status': 'Deleted'}}, {upsert: false, multi: true});

How to update multiple elements in single query.Thanks in advance !!
