Ajax Update on PrimeFaces dialog disables datepicker, and textarea counters - primefaces

Question

I have a PrimeFaces dataTable with buttons at the footer for creating, editing and deleting records from the table.
A click on the Create and Edit button displays a modal dialog to carry out each task. During a create or Edit, the dialog is not dismissed but rather an Ajax update is done so that as many record as possible can be inserted or edit can be repeatedly done. But the issue now is, after any Ajax Update datepickers gets disabled and TextArea counters disappears. Code sample is available below:
<ui:define name="metadata">
<f:metadata>
<f:event listener="#{departmentController.retrieveDeptList}"
type="preRenderView"/>
