i'm using a modal to hold my form, the modal contains this commandbutton

<p:commandButton styleclass="btn btn-primary" action="#{testController.create}" oncomplete="handleComplete(xhr, status, args)" />

handleComplete function:

function handleComplete(xhr, status, args) {  
    if(args.validationFailed) {  
        alert("failed");
    }else{
        $('#test-modal').modal('hide');

          // Do something here to reload the datatable to add the newly created item

    }
}

You can use <p:remoteCommand> to generate a JavaScript function which invokes a JSF command action.

<h:form>
   <h:dataTable id="table" value="#{testController.items}" var="item" border="0">
       <h:column>
           <h:outputText value="#{item.name}"/>
       </h:column>           
   </h:dataTable>
   <p:remoteCommand name="updateTable" action="#{testController.update}" update="table" />
</h:form>

This can be invoked as follows:

function handleComplete(xhr, status, args) {  
    if (args.validationFailed) {  
        alert("failed");
    } else {
        $('#test-modal').modal('hide');
        updateTable();
    }
}
