Can't remove items from the selectMenu

Question

I am using selectMenu as:
<a4j:region selfRendered="true"  id="text">
            <h:selectOneListbox id="symbol" value="#{user.name}">
              <f:selectItems value="#{user.temp_list}" />
          </h:selectOneListbox>
<a4j:commandButton action="#{user.getData}" reRender="symbol" value="Get"/>
</a4j:region>temp_list has following three values when page loads:
temp_list.add(new SelectItem("Sunday"));
temp_list.add(new SelectItem("Monday"));
temp_list.add(new SelectItem("Tuesday"));Now in user.getData i want to remove items one by one based on the selection made by the user. The code is:
temp_list.remove(0);
this.setTemp_list(temp_list);But the problem is that if user selects Sunday for example, it remove it from the list but next time when user select Monday it removes monday but BRING BACK SUNDAY AGAIN IN THE LIST. Why is it so?

I don´t understand you.Actually i was asking about the code which i mentioned in my last post.
Okay then what could be the solution? What my thinking is that calling list.remove actually removes the item from the list permenantly, isn't it? If so then why does it showing me again in the selectMenu?
