Try creating your checkbox like this, with a proper boolean model:
add(new CheckBox("check", new IModel<Boolean>() {
public Boolean getObject() {
return pax.contains((Passenger) item.getModelObject());
}
public void setObject(Boolean bool) {
if (bool) {
pax.add((Passenger) item.getModelObject());
} else {
pax.remove((Passenger) item.getModelObject());
}
}
public void detach() {
// no-op
}
}));
