automatically status flipping in RTC 5.0.2 from resolved to closed

How can i Flip the status of workitem from 'Resolved' to 'Closed' automatically after 48 hours.

i can see that we can write our own condition in Dojo. So itried one but i am not sure how that is going to work.

1: Shall i create a dummy types and attribute and set that as to take calculated data.

2: How can i compile my code in RTC to check if it there is any error and if so then what error.

3: please review my first piece of code written in Dojo to achieve this.

dojo.provide("com.CalHEERS.ResolvedToClosed");

dojo.require("com.ibm.team.workitem.api.common.WorkItemAttributes");

dojo.require("dojo.date");

dojo.require("dojo.date.stamp");

(function() {

var WorkItemAttributes= com.ibm.team.workitem.api.common.WorkItemAttributes;

    dojo.declare("com.CalHEERS.ResolvedToClosed", null, {

    getValue: function(attribute, workItem, configuration) {

  var currentDate = new Date();

  var currentDateString = dojo.date.stamp.toISOString(currentDate, {milliseconds:true, zulu:true});

  var resolutionDate = dojo.date.stamp.fromISOString(workItem.getValue(com.ibm.team.workitem.attribute.resolutiondate));

  var SRStatus = workItem.getValue(com.ibm.team.workitem.attribute.state);

        If (((SRStatus == "Resolved") || (SRStatus == "SR.action.a7")) && (currentDateSting.getTime() - resolutionDate.getTime() >= 2))

  {

   SRStatus = "Closed";

        }

  else

  {

   SRStatus = "Resolved"

  }

   }

})

})();

So please on the same.
