RTC - The Value set is not activate .

Hello
I  am  trying  to activate  the  Value  set  on  deliverable  field   .
The  value  set is  not  activated ,  I  do not  get error  , it  just  is  not  working.
I have tried to  set  the example  value  set  to  Small String  field and  it  is  not  working  also  . 


My  script  is  :
dojo.provide("SetDeliverableField");
dojo.require("com.ibm.team.workitem.api.common.WorkItemAttributes");
dojo.require("dojo.string");


(function() {
var WorkItemAttributes= com.ibm.team.workitem.api.common.WorkItemAttributes;

dojo.declare("SetDeliverableField", null, {

    getValueSet: function(attributeId, workItem, configuration) {
        var result= [];
       

        var csci= workItem.getValue(WorkItemAttributes.FILED_AGAINST);
        console.log(release);
       
     
       
           var found= false;
    
        var allReleases= configuration.getChildren("release");
        for (var i= 0; i < allReleases.length; i++){
            var r= allReleases[i];
             var releaseName= r.getString("uuid")
            if (releaseName.indexOf(csci)>-1) {
                // If there is a configuration entry for this release use it
                found= true;
                result.push(releaseName)
                }
            }
        }
       
     
        if (!found) {
            for (var i= 0; i < allReleases.length; i++){
            var r= allReleases[i];
             var releaseName= r.getString("uuid")
            result.push(releaseName)
              }
        }
       
        return result;
    }

Please advice  ...
Thanks  in advance.
