不會更改jsf上的outputtext值

我用primefaces製作了一個web項目。我將一個txt文件上傳到數據表中，然後創建一些特定的過程，然後想要對assign列進行一些更改，但是當我輸入某些內容時，outputtext不會更改。但是，輸入文本更改。我的意思是如果該行點擊，顯示新值，但它不顯示舊值。這裏是我的代碼不會更改jsf上的outputtext值

@[email protected] public class MessageTableController implements Serializable { 

private static final long serialVersionUID = 20111020L; 

private List<preList> kullaniciList; 
private UploadedFile file; 
private File f; 
private BufferedReader br; 
private String line; 
private String[] str; 


public List<preList> getKullaniciList() { 
    return kullaniciList; 
} 

public void setKullaniciList(List<preList> kullaniciList) { 
    this.kullaniciList = kullaniciList; 
} 

public UploadedFile getFile() { 
    return file; 
} 

public void setFile(UploadedFile file) { 
    this.file = file; 
} 

public void upload() throws IOException { 
    if (file != null) { 
     FacesMessage message = new FacesMessage("Succesful", file.getFileName() + " is uploaded."); 
     FacesContext.getCurrentInstance().addMessage(null, message); 
     readUploadedFile(); 
    } 
} 

public void readUploadedFile() throws IOException { 
    f = new File(file.getFileName()); 
    br = new BufferedReader(new FileReader(f)); 
    kullaniciList = new ArrayList<preList>(); 
    while ((line = br.readLine()) != null) { 
     if (line.contains("PI")) { 
      str = line.split("="); 
      kullaniciList.add(new preList(str[0], str[1])); 
     } 
    } 
    br.close(); 
} 


public class preList { 

    private String value; 

    private String assign; 

    public preList(String value, String assign) { 
     this.value = value; 
     this.assign = assign; 
     System.out.println(value); 
    } 

    public String getValue() { 
     return value; 
    } 

    public void setValue(String value) { 
     System.out.println(value); 
     this.value = value; 
    } 

    public String getAssign() { 
     return assign;

    public void setAssign(String assign) { 
     System.out.println(value);

的Primefaces Showcase使用

<p:ajax event="cellEdit" listener="#{dtEditView.onCellEdit}" update=":form:msgs" />

所以更新的形式，而不是數據表，併爲輸入字段沒有更新的屬性。
