Problem With the "action" Attribute

Hi,
I want to edit some of my table data. I have put <h:commandButton> around my <h

utputText ...> so that if I click on the button, the changes would be saved to database. The action of the button is : "tableData.saveEditedRow".
The problem is that when I click on the button nothing happens.
These are some part of my code (please kindly help me) :

edit.jsp :

TableData.java :

package com.corejsf;
 
import javax.faces.component.html.HtmlDataTable;
 
public class TableData {
   private static final Name[] names = new Name[] {
       new Name("William", "Dupont"),
       new Name("Anna", "Keeney"),
       new Name("Mariko", "Randor"),
       new Name("John", "Wilson")
   };
   private Name name = new Name();
 
    private HtmlDataTable myDataTable;
   public Name[] getNames() { 
       return names;
   }
   
   public String saveEditedRow() {  
      name = (Name) getMyDataTable().getRowData();
      System.out.println("***" + name.getFirst());
      return "success";
   }  
   
  // Getters ----------------------------------------------------------
 
    public HtmlDataTable getMyDataTable() {
        return myDataTable;    
    }
 
    public Name getMyDataItem() {
        return name;
    }
 
    // Setters ----------------------------------------------------------
 
    public void setMyDataTable(HtmlDataTable myDataTable) {
        this.myDataTable = myDataTable;
    }
 
    public void setMyDataItem(Name name) {
        this.name = name;
    }
}

My bean class (Name.java) :

Please somebody guide me...

On the line
<h:commandButton action="tableData.saveEditedRow" value="save">

you must surround "tableData.saveEditedRow" with #{} so it becomes

<h:commandButton action="#{tableData.saveEditedRow}" value="save">
