GWT SimplePager on CellTable is not Updating

The code below works on initialization, however if you add new data, it does not display the updated row.

Previous Code :
CellTable table = new CellTable();
SimplePager.Resources pagerResources = GWT.create(SimplePager.Resources.class);
pager = new SimplePager(TextLocation.CENTER, pagerResources, false, 0, true);
pager.setDisplay(table);
pager.setPageSize(10);
table.setPageSize(10);
ListDataProvider dataProvider = new ListDataProvider();
dataProvider.addDataDisplay(table);
List list = dataProvider.getList();
for (Carrier contact : data) {
list.add(contact);
}


Fix :
pager.startLoading();

Current Code :
CellTable table = new CellTable();
SimplePager.Resources pagerResources = GWT.create(SimplePager.Resources.class);
pager = new SimplePager(TextLocation.CENTER, pagerResources, false, 0, true);
pager.setDisplay(table);
pager.setPageSize(10);
table.setPageSize(10);
pager.startLoading();
ListDataProvider dataProvider = new ListDataProvider();
dataProvider.addDataDisplay(table);
List list = dataProvider.getList();
for (Carrier contact : data) {
list.add(contact);
}
