I have created a generalised solution  The function below will change ids and names of cloned object  In most cases  you will need the row number so Just add  data-row-id  attribute to the object    function renameCloneIdsAndNames  objClone          if   objClone attr   data-row-id                console error   Cloned object must have   data-row-id   attribute                 if  objClone attr   id                objClone attr   id   objClone attr   id    replace    d     function  strId     return parseInt  strId     1                    objClone attr   data-row-id   objClone attr   data-row-id    replace    d     function  strId     return parseInt  strId     1              objClone find    id     each  function              var strNewId      this   attr   id    replace    d     function  strId     return parseInt  strId     1                   this   attr   id   strNewId             if     this   attr   name                    var strNewName       this   attr   name    replace      d    g  function  strName                     strName   strName replace            g                        var intNumber   parseInt  strName     1                  return       intNumber                                       this   attr   name   strNewName                           return objClone

Update  As Roko C Bulijan pointed out   you need to use  insertAfter to insert it after the selected div  Also see updated  code if you want it appended to the end instead of beginning when cloned multiple times  DEMO  Code      var cloneCount   1         button   click function              id              clone              attr  id    id   cloneCount               insertAfter   id  id  last                              -- Use   id  if you want to insert the cloned                               element in the beginning            text  Cloned      cloneCount-1       lt --For DEMO             Try       id   clone   attr  id    id1   after   id      If you want a automatic counter  then see below      var cloneCount   1        button   click function              id   clone   attr  id    id   cloneCount    insertAfter   id
