Issue in displaying p:messages for converterMessage - jsf

Question

I am using PrimeFaces but I have problem with display <p:messages> for converterMessage.
When I use JSF tag <h:message>, it works correctly or even when I insert it into columns, but when I change to <p:message> it does not show. Can anybody helps me? My page is:
<h:form id="form2" prependId="false" style="direction:rtl;width: 600;top: 300px ;position: absolute" >
<p:messages for="count"/>
<p:outputLabel value="sum credit :#{shoppingBean.sumcredit}"/><br/>
<p:outputLabel value="shopping list :"/>
<p:dataTable id="dataTbl2" var="selectedProduct" value="#{shoppingBean.selectedProduct}" emptyMessage="no data"
paginatorAlwaysVisible="true" selection="#{shoppingBean.selection2}"
rowKey="#{selectedProduct.id}" disabledSelection="false" rows="5" paginator="true" pageLinks="5">
<p:column style="color: blue">
<f:facet name="header">
<h:outputText value="brand" />
</f:facet>
<h:outputText value="#{selectedProduct.tblShopProduct.brand}" />
</p:column>
<p:column style="color: blue">
<f:facet name="header">
<h:outputText value="price" />
</f:facet>
<h:outputText value="#{selectedProduct.tblShopProduct.price}" />
</p:column>
<p:column style="color: blue" >
<f:facet name="header">
<h:outputText value="date" />
</f:facet>
<h:outputText value="#{shoppingBean.tblShopOrder.created.toString().substring(0,11)}" />
<h:outputText value="#{shoppingBean.tblShopOrder.created.toString().substring(11,19)}" />
</p:column>
<p:column style="color: blue" >
<f:facet name="header">
<h:outputText value="number" />
</f:facet>
<h:outputText value="#{selectedProduct.number}" />
</p:column>
<p:column style="color: blue" >
<f:facet name="header">
<h:outputText value="amount" />
</f:facet>
<h:outputText value="#{selectedProduct.amount}" />
</p:column>
<p:column style="color: blue">
<f:facet name="header">
<h:outputText value="edit"/>**<h:inputText id="count" converterMessage="you allowed only for using number value="#{shoppingBean.count}"/>**
</f:facet>
<h:commandButton value="sum" rendered="#{selectedProduct.number==null}" action="#{shoppingBean.addProductCount(selectedProduct)}" />
<h:commandButton value="confirm" disabled="true" rendered="#{selectedProduct.number!=null}" />
</p:column>
<p:column style="color: blue" >
<f:facet name="header">
<h:outputText value="delete" />
</f:facet>
<h:commandButton value="delete" action="#{shoppingBean.deleteBuyed(selectedProduct)}" />
</p:column>
<f:facet name="footer">
<h:commandButton value="final shopping" action="#{shoppingBean.finalShop(selectedProduct)}" />
</f:facet>
</p:dataTable>
</h:form>

<h:outputText value="edit"/>**<h:inputText id="count" converterMessage="you allowed only for using number value="#{shoppingBean.count}"/>**
This line could not work. Fix this first.
You do not update your messages tag.
Try something like this :
<p:messages for="count" autoUpdate="true" />
