Copying objects from EPC model to FAD model

Hello all!
I wanna copy all occurrences of objects from EPC to FAD, which TypeNum of icon is 39 (ST_SCRN) and which have a relationships with functions.
But my script has an error.
Tell me please how can I fix this error. May be I have to other function instead "createCopy"?

This is my code:

function f1(){
   for(var i = 0; i < aModels.length; i++){     
      var oModel = aModels[i];                 
      var aFuncObj = oModel.ObjOccListFilter(Constants.OT_FUNC);   
      for (var j = 0; j < aFuncObj.length; j++) {                  
         if(aFuncObj[j].SymbolNum() == 335){                        // Take only functions which SymbolNum == 335 (ST_FUNC)
            var transListFunc = new Array;                         
            var transListFunc = aFuncObj[j].getConnectedObjOccs ( [ Constants.ST_SCRN],  Constants.EDGES_INOUT );
            if (transListFunc.length!=0){                                       
               var gr = GetOrCreateGroup(oModel, "Транзакции");              // Create group "Transactions"
               var fadModel = GetOrCreateModel(gr, aFuncObj[j].ObjDef().Name(1049), Constants.MT_FUNC_ALLOC_DGM); // Create FAD-model which names as function name which have transactions
               aFuncObj[j].ObjDef().CreateAssignment(fadModel);                     
               for( var t = 0; t < transListFunc.length; t++ ) {    // Iterate all transactions, which have relations aFuncObj[j]
                  //This I wanna use function, that copy objects to FAT
                  createCopy ( fadModel, transListFunc[t].OccList() );  // Error: "createCopy" is not defined
               }
            }
         }
      }
   }
}
