JSF + primefaces spinner ajax invoking other submits - ajax

Question

I'm using ajax in spinner to call some action in backing bean.
this is my code:
<b:panel>
<p:dataTable id="orderDataTable" var="order" value="#{orderViewBean.orders}"
widgetVar="ordersDataTable" tableStyle="table-layout: auto;">
<p:column headerText="Created" filterBy="#{order.creationDate}" filterStyle="display: none"
filterMatchMode="contains">
<h:outputText value="#{order.creationDate}"/>
</p:column>
<p:column headerText="Created By" filterBy="#{order.createdBy}" filterStyle="display: none"
filterMatchMode="contains">
<h:outputText value="#{order.createdBy}"/>
</p:column>
</p:dataTable>
<b:panelGrid colSpans="4,4,4">
<b:commandButton action="#{orderViewBean.previousPage}" value="Previous"
look="primary" process="#this:uploadOrderDataPanel" styleClass="pull-left"
disabled="#{!orderViewBean.page.hasPrevious()}" type="submit">
<p:ajax immediate="true" update=":companyOrdersForm"/>
</b:commandButton>
<b:row>
<div class="text-center">
<h:outputLabel value="Page"/>
<p:spinner value="#{orderViewBean.currentPage}" size="3"
min="#{orderViewBean.page.totalPages > 0 ? 1 : 0}"
max="#{orderViewBean.page.totalPages}">
<p:ajax listener="#{orderViewBean.changePageAjax}"
update="#form" process="#this" immediate="true"/>
</p:spinner>
<h:outputLabel value="Of"/>
<h:outputText value="#{orderViewBean.page.totalPages}"/>
</div>
</b:row>
<b:commandButton action="#{orderViewBean.nextPage}" value="Next"
look="primary" process="#this:uploadOrderDataPanel" styleClass="pull-right"
disabled="#{!orderViewBean.page.hasNext()}" type="submit">
<p:ajax immediate="true" update=":companyOrdersForm"/>
</b:commandButton>
</b:panelGrid>
</b:panel>
When I put some number into spinner and hit enter, then changePageAjax is invoked (this is ok) and also orderViewBean.previousPage (this is not ok). Can I avoid invoking other actions?

Add a partialSubmit="true" attribute on the relevant ajax tags.. From the PF documentation:
PartialSubmit reduces network traffic by only adding the partially processed components to the ajax request post. For big pages with many input components, partialSubmit is extremely useful as it leads to more lightweight requests. Compare the Post Data displayed by the logger for the difference.
