Ajax render attribute not working in h: dataTable in JSF2

I have a problem with a simple application in JSF 2.0.

I am trying to create a ToDo list with ajax support. I have some todo lines that I'm showing using data. Inside this datatable, I have commandLink to delete the task. The problem is that data is not being returned repeatedly.

    <h:dataTable id="todoList" value="#{todoController.todos}" var="todo">
        <h:column>
                <h:commandLink value="X" action="#{todoController.removeTodo(todo)}">
                    <f:ajax execute="@this" render="todoList" />
                </h:commandLink>
        </h:column>
        <h:column>
            <h:outputText value="#{todo}"/>
        </h:column>
    </h:dataTable>

Thank you for your help.

Edit (TodoController):

@ManagedBean
@SessionScoped
public class TodoController {

private String todoStr;
private ArrayList<String> todos;

public TodoController() {
    todoStr="";
    todos = new ArrayList<String>();
}

public void addTodo() {
    todos.add(todoStr);
}

public void removeTodo(String deleteTodo) {
    todos.remove(deleteTodo);
}

/* getter / setter */
}
