Business Method API - Javascript Array not saving

Question

Hello.  I am building a business method that stores a list of URLs in an array.  I followed the sample documentation for "using_arrays" at https://streamwork.com/api/methods/com.streamwork.using_arrays.zip.
The insert, update, delete calls work while my method is on screen.  However, nothing seems to save.  As soon as I switch to a different activity and back, my method returns to its initial state.
Here are my handlers:
var handlers = {
    data_inserted: function(data) {
      arrSAPLaunch.push(data);
      RenderTable();
    data_updated: function(data) {
      for(i=0;i<arrSAPLaunch.length;i++) {
        if(arrSAPLaunch<i>.id==data.id) {
          arrSAPLaunch<i> = data;
          break;
      RenderTable();
    data_deleted: function(data) {
      for(i=0;i<arrSAPLaunch.length;i++) {
        if(arrSAPLaunch<i>.id==data.id) {
          arrSAPLaunch.splice(i,1);
          break;
      RenderTable();
    // RUNS ONCE THE MODULE IS LOADED
    started: function()     {
      BuildSAPLiterals();
      RenderControl(Control_Area, initialData.myData);
... and here are my calls....
handlers.clientChannel.publish({type: "delete_array_item", data: {path: "arrSAPLaunch", id: arrSAPLaunch<b>.id }});
handlers.clientChannel.publish({type: "insert_array_item", data:{path: "arrSAPLaunch", value: GetLaunchItem()}});
handlers.clientChannel.publish({type: "update_array_item", data: {path: "arrSAPLaunch",id: arrSAPLaunch[vIndex].id, value: GetLaunchItem()}});
... where GetLaunchItem is a function that returns a javascript object with three properties.
Any idea why this code is not saving to the SAP Streamwork server?

I changed the calls to use the array named in the initialData object (originally specified in the bundle.xml file).  It appears that this is one way to declare the persistent array to the Streamwork system (there may be others but I did not see this in documentation).
handlers.clientChannel.publish({type: "delete_array_item", data: {path: "arrSAP", id: arrSAPLaunch<b>.id }});
handlers.clientChannel.publish({type: "insert_array_item", data:{path: "arrSAP", value: GetLaunchItem()}});
handlers.clientChannel.publish({type: "update_array_item", data: {path: "arrSAP",id: arrSAPLaunch[vIndex].id, value: GetLaunchItem()}});
