p:autocomplete stops working after updating parent via ajax - primefaces

Question

I have a list of autocompletes that is rendered using a p:dataList. Something like shown below:
<h:panelGroup layout="block" id="outerPanel">
<p:dataList rendered="#{bean.myModel.listOfItems.size()>0}"
var="additionalMP"
value="#{bean.myModel.listOfItems}"
rowIndexVar="index" emptyMessage="">
<div class="wrapper ui-g">
<div>
<p:autoComplete
cache="true"
value="#{bean.myModel.listOfItems[index]}"
completeMethod ="#{handler.getAutoCompleteData}"
rendered ="true"
required="false"
scrollHeight="200"
styleClass="custom"
forceSelection="true">
<p:ajax event="query" global="false"/>
<f:attribute name="filter" value="filterName" />
<f:attribute name="mode" value="edit" />
</p:autoComplete>
</div>
<div>
<p:commandLink value="+ Add" actionListener="#{bean.addAutoComplete()}"
update=":formName:outerPanel"></p:commandLink>
</div>
</div>
</p:dataList>
</h:panelGroup>
So, the Add button inserts a new item in the list and I update the container panel so that the newly added item can be rendered on the UI.
As expected the panel is updated and I see another autocomplete on the UI. But the problem is, all the auto completes now don't work. i.e. they stop firing the query event and don't give any suggestions.
Edited: The partial response that updates the section of form with autocomplete fields, contains some script tags, which probably execute on page ready/load event. So I know that basically the newly added prime faces widgets are not being initialized.
Any idea how I can initialize the newly added autocompletes in the DOM?

Answer 1

The reason for all this trouble was an error in javascript that was caused by trying to scrollTo a particular element on the page from the bean. This crappy line of code in the bean was the source of all the trouble. There was no element on the page with the id messages. A glaring example of why UI should not be coupled in such a way.
RequestContext.getCurrentInstance().scrollTo("formId:messages");
