Adding User_Notes to Opportunity

Hi all,

I'm attempting to create an Opportunity record and add individual User_Notes line items to the Opportunity within a RESTlet. The Opportunity is being created fine, but the line items refuse to appear and no errors are thrown. Would appreciate any ideas you all may have on what I am missing here. Thanks!

This is the code in use:

function addNoteToOpportunity(record, note)  {      record.selectNewLineItem('usernotes');      record.setCurrentLineItemValue('usernotes', 'note', note.note);      record.setCurrentLineItemDateTimeValue('usernotes', 'noteDate', note.datetime, 'America/Chicago');      record.setCurrentLineItemValue('usernotes', 'direction', note.direction);      record.commitLineItem('usernotes');  }    function createOpportunity(dataIn)  {      // Add basic fields      var record = nlapiCreateRecord('opportunity');      record.setFieldValue('title', dataIn.title);      record.setFieldValue('entity', dataIn.customer_id);      record.setFieldValue('custbody33', dataIn.ticket);        var i = 0;        for ( ; i < dataIn.notes.length ; ++i)      {          addNoteToOpportunity(record, dataIn.notes[i]);      }        nlapiLogExecution('DEBUG', 'test', 'Notes: ' + nlapiGetLineItemCount('usernotes'));            // Save the record      var oppId = null;      try {          oppId = nlapiSubmitRecord(record, true, true);      } catch (ex) {          nlapiLogExecution('ERROR','inventory rest error', 'create opportunity: ' + ex.message);          return {              'status' : 'fail',              'message' : 'error creating opportunity: ' + ex.message          };      }        // Reload
