I have a visualforce page with a StandardController="Quote" and an extension controller.  I need to pull up a list of some of the QuoteLineItems, related to the quote display them in inputfields, update them on the visualforce page, then save the updated records.  I have no problem bringing up the records and displaying them, however when I go to update the records, the records are not updated.   Have tried everything, including the documentation, but nothing seems to be working.  Seems simple, I must be doing something fundamentally wrong.

Here is the relevant markup:

<apex:page StandardController="Quote" Extensions="AddPartController" wizard="true">

    <apex:Pageblock Title="STEP 2: Add the New Products to your Quote Here" >

        <apex:pageblockbuttons location="top">

            <apex:form >
                <apex:commandButton Value="Add to Current Quote" action="{!AddToCurrentQuote}" />

            </apex:form>
        </apex:pageblockButtons>
        <br/>

            <apex:datatable value="{!PendingQuoteLineItemList}" var="qli" width="100%">

               <apex:column headerValue="Product Alias" style="width:100px" >
                   <apex:inputfield value="{!qli.Product_Alias__c}" />

And here is the relevant Controller code:

Hi - I can't seem to figure out how to get my setter method to bind to my page.  The none of my setter methods are being called.
