In addition to the other answers  I d like to improve the removal  to something more generic     this  closest  tr   remove      This would be much better than using   this  parent   parent   remove     because it doesn t depend on the depth of the element  So  the structure of the row becomes much more flexible

You only can have one unique ID per page  Change those IDs to classes  and change the jQuery selectors as well   Also  move the  on   outside of the  click   function  as you only need to set it once   http   jsfiddle net samliew 3AJcj 2     document  ready function            addCF   click function                customFields   append   lt tr valign  top  gt  lt th scope  row  gt  lt label for  customFieldName  gt Custom Field lt  label gt  lt  th gt  lt td gt  lt input type  text  class  code  id  customFieldName  name  customFieldName    value    placeholder  Input Name    gt   amp nbsp   lt input type  text  class  code  id  customFieldValue  name  customFieldValue    value    placeholder  Input Value    gt   amp nbsp   lt a href  javascript void 0    class  remCF  gt Remove lt  a gt  lt  td gt  lt  tr gt                     customFields   on  click    remCF  function              this  parent   parent   remove

There are multiple problems here   Id should be unique in a page For dynamic elements  you need to use event delegation using  on     Ex    document  ready function            addCF   click function                customFields   append   lt tr valign  top  gt  lt th scope  row  gt  lt label for  customFieldName  gt Custom Field lt  label gt  lt  th gt  lt td gt  lt input type  text  class  code  id  customFieldName  name  customFieldName    value    placeholder  Input Name    gt   amp nbsp   lt input type  text  class  code  id  customFieldValue  name  customFieldValue    value    placeholder  Input Value    gt   amp nbsp   lt a href  javascript void 0    id  remCF  gt Remove lt  a gt  lt  td gt  lt  tr gt                      customFields   on  click     remCF   function              this  parent   parent   remove                   Demo  Fiddle  See this demo where id properties are removed     document  ready function            addCF   click function                customFields   append   lt tr valign  top  gt  lt th scope  row  gt  lt label for  customFieldName  gt Custom Field lt  label gt  lt  th gt  lt td gt  lt input type  text  class  code  name  customFieldName    value    placeholder  Input Name    gt   amp nbsp   lt input type  text  class  code  name  customFieldValue    value    placeholder  Input Value    gt   amp nbsp   lt a href  javascript void 0    class  remCF  gt Remove lt  a gt  lt  td gt  lt  tr gt                      customFields   on  click     remCF   function              this  parent   parent   remove
