JSF

Dear I have a JSF project and want to update a row in JSF datatable.
I have a database which called domain has columns
domainName
failed
na
inProgress.

<h:dataTable value="#{UserBeanClass.selectedDomainList}" var="domains">
									
									<h:column>
										<f:facet name="header">Domain Name</f:facet>
										<h:inputText value="#{domains.domainName}"></h:inputText>
									</h:column>
								   
									<h:column>
										<f:facet name="header">Failed</f:facet>
										<h:inputText value="#{domains.failed}"></h:inputText>
									</h:column>
										   
									<h:column>
										<f:facet name="header">NA</f:facet>
										<h:inputText value="#{domains.na}"></h:inputText>
									</h:column>
										   
									<h:column>
										<f:facet name="header">In Progress</f:facet>
										<h:inputText value="#{domains.inProgress}"></h:inputText>
									</h:column>
										   
									<h:column>
										<f:facet name="header">Actions</f:facet>
										<h:form>
											<h:commandLink action="#{UserBeanClass.UpdateDomain(domains)}"></h:commandLink>
											<h:commandLink action="#{UserBeanClass.DeleteDomain(domains)}">^__i class="icofont-ui-delete"></h:commandLink>
										</h:form>
									</h:column>
</h:dataTable>

and my Java code

public String UpdateDomain (Domains domain) {
		DomainOperations domainOperations = new DomainOperations();
		if(domainOperations.updateDomain(domain) > 0) {

		return "edit";
	}
}

What I have tried:

Code works but domains value is never going to change, its value remain still the same.

Could you help me?
