Hiding few Items in replicant on (+)

Team

I want to hide few items when i click on (+) Add replicant.

Here is the scenario:
I have 2 textareas - Item1 and item2. When a user clicks on (+) to add a replicant - only Item 1 should be replicated and not item2.
I used OnReplicantAdded event but there seems to be some error due to which i cannot see the effect. I am also using a CONTAINER.

Here is what i have so far:

THE DCT code:
<item name="DText">

<label>Item 1:</label>
<replicant min="1" max="unbounded">
<item name="item1">
<description>Item 1description>
<label>Item 1</label>
<text required="t" size="50" maxlength="500"/>
</item>
<item name="Item2">
<label>Item2</label>
<text required="f" size="50" maxlength="500"/>
</item>

</replicant>
</item>

I added the Formapi Under <Ruleset> but before <container> starts:
<ruleset name="Item Test">

<script>
<![CDATA[
<!-- ===== HIDE SUBHEADER CODE ==== -->
IWEventRegistry.addItemHandler("/DText","OnReplicantAdded",Hide_SubHeader);
function Hide_Subheader()
{
for (var i=1;i<=IWDatacapture.getItem('/DText').getChildren().length;i++)
{
alert("Entering Replicant Event");
IWDatacapture.getItem('/DText[' + i + ']/item2').setVisible(false);
}
}
]]>
</script>


Also if i am using a CONTAINER - Do i have to refer container name somewhere in the URL or IWDATAcapture?

Will OnReplicantBeforeAdd work?
