How to set the readonly property of the dynamic text box by using jQuery?

I'm trying to fill a textbox from DB values and I want to set textbox value readonly. When the user clicks on an EDIT option then set all textboxes become editable. I have failed to achieve this. Here is my HTML code:

<html>
  <head>
    <script>
      $(document).ready(function() {
        $('#contentid :input').each(function() {
          $(this).attr("disabled",true);
        });

      $('#edit').on('click',function() {
        $('#contentid :input').each(function() {
          $(this).attr('disabled',false);});
        });
     });
   </script>
</head>

<body>
  <div data-role="page" id="viewInformation" data-theme="d" data-add-back-btn="true" data-back-btn-text = "back">
    <div data-role="header" id="headerid" class="ui-bar ui-bar-b">
      <h3></h3>
    </div>

    <div data-role="content" id="contentid">
      <a href="#" id="saveDBValue" data-role="button" data-mini="true" style="width:60px; height:40px; float:center;">SAVE</a>
      <a href="#" id="edit" data-role="button">EDIT</a>
    </div>
  </div>
</body>

Here is my JavaScript code:

 function getDataofSelectedListItem()
    {
        alert("getDataofSelectedListI");
        clickedListItem = window.localStorage.getItem("clickedValueofList");
        console.log("clicked list item"+clickedListItem);
        //db = window.openDatabase("loginintro", "1.0", "loginintro", 1000000);
        var sqlQuery = 'SELECT * FROM loginTable WHERE username=\''+window.localStorage.getItem("clickedValueofList").trim()+'\';';

        console.log("selected list query:"+sqlQuery);
        db.transaction(function(tx)
        {
          tx.executeSql(sqlQuery,[],successCBofListItem,errorCBofListItem);
        },errorCB,successCB);
    }
    function successCBofListItem(tx,results)
    {   alert("erer");
      if(results != null && results.rows != null && results.rows.length > 0)
         {  $('#contentid').append('<label>UserName:</label><input content-editable="false" id="name" type="text"   value="'+results.rows.item(0).username+'"/>');
         $('#contentid').append('<label>EMAIL ID:</label><input type="text" value="'+results.rows.item(0).emailid+'"/>');
         $('#contentid').append('<label>Password:</label><input type="text" value="'+results.rows.item(0).password+'"/>');
    }
    function errorCBofListItem()
    {
        alert("errorCBofListItem");
    }

What am I doing wrong?

You have to use live for capturing the click event

$('#edit').live('click',function()

I have created an Example
