HTML Client: post process a preprocess query?

Question

I am trying to set up a method for quoting jobs and keeping track of parts for the quote. Many quotes can have many parts, so I have a many to many relationship between Quotes and Parts via a table called QuoteParts.
I am trying to design an Add Edit Quote screen with two tabs: one has the quote details and a list of parts for this quote. The other tab has a list of parts available to go on the quote. I have it set so when you tap the item in the list not added to the
quote, it adds the QuotePart and the part moves from the list of available parts to the quote. 
I am filtering the two lists using two preprocess queries. They both work fine when opening the screen, however when I add a new part, the part shows up in both lists. I'm assuming it's because the preprocess query didn't preprocess, since the data was added
to the screen and has not been saved yet. If I save and reopen the screen, all shows up fine. 
So on to my question: Is there any way to POST process a preprocess query?
I got the idea of how to work with this via http://blogs.msdn.com/b/lightswitch/archive/2013/04/10/many-to-how-many-html-edition-heinrich-wendel.aspx

Close, try this:
myapp.BrowseParts.AddPart_execute = function (screen) {
myapp.showAddEditPart(null, {
beforeShown: function (newScreen) {
var newPart = new myapp.Part();
newPart.Hardware = screen.Hardware;
newScreen.Part = newPart;
}, afterClosed: function (newScreen, navigationAction) {
if (navigationAction === msls.NavigateBackAction.commit) {
// Save all changes to parts
return myapp.activeDataWorkspace.ApplicationData.saveChanges().then(function () {
// Refresh the Parts that other code does not reach
screen.UsedParts.refresh();
screen.UnusedParts.refresh();
Be careful about creating global scope functions like you did: RefreshPartsLists.
