Line item data is not saving while creating a Sales order using Interactive

Question

Hi all,
I am creating a sales order Using Interactive forms. In the form i am having Header data and line item data.I had created two structures one for Header data and one for Line item data. For entering  the LINE ITEM DATA i had created a Dynamic table with Buttons ADD ROW and DELETE ROW.
User will Add the Row or Delete the Row based on the requirement.
My issue is When ever the user clicks the SUBMIT button after entering the header data and 3 line items data , Sales order has been created with only first line item and the remaining two line items are not created.
My Interactive form is like below
HEADER DATA
DOC_TYPE
SALES_ORG
DIST_CHN
DIVISION
PURCH_NO
PARTN_ROLE
PART_NO
LINE ITEM DATA
                         ITEM_NO      MATERIAL          PLANT          QTY        COND_TYPE            COND_VALUE
ADD ROW
DELETE ROW
                                                                                SUBMIT
My  code for the method ONACTIONCLICK is like below

PLEASE SUGGEST ME IF ANY CODE CHANGE IS REQUIRED
Thanks in advance

Hi,
The item data is not read because, the dynamically added rows should also reflect back to the Web Dynpro context. When the user clicks on Add Row, use the Onsubmit event to add a empty line to internal table and then bind it to the context. And if the user removes a row, remove a row from internal table and bind it back to the context.
