How to update specific inputText in dataTable to be enabled or disabled based on rowSelect event

I need your help in updating a specific inputText component to be enabled in a dataTable once the checkbox in the row is ticked. Here is the code for the dataTable:

<h:form id="request">
      <p:dataTable value="#{dataTableView.employeeList}" id="Employee" var="emp"
                             selection="#{dataTableView.selectedEmployees}" rowKey="#{emp.id}">
      <p:ajax event="rowSelectCheckbox" listener="#{dataTableView.EnableInputText}" />
      <p:ajax event="rowSelect" listener="#{dataTableView.EnableInputText}" />
             <p:columnGroup type="header">
               <p:row>
               <p:column/>
             <p:column headerText="ID"/>
             <p:column headerText="Name"/>
             <p:column headerText="Location"/>
             <p:column headerText="Remarks"/>
               </p:row>
              </p:columnGroup>
           <p:column selectionMode="multiple" style="width:2%;text-align:center"/>
           <p:column headerText="ID">
           <h:outputText value="#{emp.id}"/>
           </p:column>
           <p:column headerText="Name">
           <h:outputText value="#{emp.name}"/>
           </p:column>
           <p:column headerText="Location">
           <h:outputText value="#{emp.location}"/>
           </p:column>
           <p:column headerText="Remarks">
           <h:inputText id="inputT1" value="#{emp.remarks}" disabled="#{emp.disable}"/>
                    </p:column>
                </p:dataTable>
            </h:form>

And the code in the backing bean:

private List<Student> employeeList = new ArrayList<Student>();
private List<Student> selectedEmployees;
private boolean disable=true;


public void EnableInputText(SelectEvent event) {
    RequestContext context = RequestContext.getCurrentInstance();


    for(int i=0;i<selectedEmployees.size();i++){ 
        for(int j=0;j<employeeList.size();j++){          
        if(selectedEmployees.get(i).getId().equals(employeeList.get(j).getId()))
        {
           selectedEmployees.get(j).setDisable(false);
            context.update("request:Employee:"+i+":inputT1");
           //employeeList.get(j).setDisable(false);
        }
       }
     }
}

Currently, I will be able to click on the checkbox but theinputText will remain disabled and I will get the error:

java.lang.UnsupportedOperationException
