Global busyIndicator for sap.m.List not working

I am trying to set busyIndicator for sap.m.List but it is not working.

Here is my xml view. I am using enableBusyIndicator true in the List like below. want to block the List for the user to do any operation.

<mvc:View  controllerName="local.controller"  xmlns:mvc="sap.ui.core.mvc"  xmlns="sap.m">  <!-- Add your XML-based controls here -->  <Button   icon="sap-icon://example"  text="Invalidate view"  press="clicked" />                                        <List                     id = "list1"  headerText="Names"
enableBusyIndicator = true         items="{path: '/names'}"        >  <StandardListItem  title="{firstname}"  counter="{lastname}"/>  </List>                      </mvc:View>
