this.datacontext.commitChanges(); is correct
I fear u didn't create the object that you are populating, into datacontext.

Check ur this.getPerfil(objid), the object that you are updating must be created into context
or by a query
SelectQuery q=new SelectQuery(this.queryClass);
List data = ctx.performQuery(q);

where data is a List of queryClass objects,
or if u want create a new object

Object o=ctx.newObject(this.queryClass);

In any case youcan check what is present into ur context:

ctx.modifiedObjects();  will return a Collection of objects that you modified
ctx.newObjects();  will return a Collection of objects that you created
