Writeback button still grayed out after all the steps I have taken

Question

Hi experts,
I have created simple writeback request, and writeback is enabled for one column, and I have placed xlm template under:
C:\OracleBI\web\msgdb\customMessages\
and my writeback button still grayed out.
Below is my xml content:
<?xml version="1.0" encoding="utf-8"?>
<WebMessageTables xmlns:sawm="com.siebel.analytics.web/message/v1">
<WebMessageTable lang="en-us" system="WriteBack" table="Messages">
<WebMessage name="target">
<XML>
<writeBack connectionPool="retail sales connection">
<insert> </insert>
<update>UPDATE market_share_target SET target_pct=@{c3} WHERE group_cd=@{c0} and region_cd=@{c1} and vehicle_ctr_cd=@{c2}</update>
</writeBack>
</XML>
</WebMessage>
</WebMessageTable>
</WebMessageTables>
Thanks very much

I added dummy sql in the <insert> section, and restarted services, still the button is greyed out.
