server-side put hidden field

Javascript (resume)

"columns": [

        { "data": "cpf" },
        { "data": "nome" , },
        { "data": "sobrenome" , },
        { "data": "celular" },
        { "data": "email" },
        {
        "data": null,
        "defaultContent": "<form method=\"post\" action=\"\"><input type=\"hidden\" id=\"idcontrib\" name=\"idcontrib\" value=\"  => "DATA": "ID" <=    \"><button type=\"submit\" class=\"btn btn-warning btn-xs\" name=\"edit_contrib\">Editar</button>&nbsp;&nbsp;<button type=\"submit\" class=\"btn btn-danger btn-xs\" name=\"exc_contrib\">Excluir</button></form>"
    },

Server-side script

 $columns = array(

array( 'db' => 'cpf', 'dt' => 'cpf' ),
array( 'db' => 'fnome',  'dt' => 'nome' ),
array( 'db' => 'lnome',  'dt' => 'sobrenome' ),
array( 'db' => 'celular1',  'dt' => 'celular' ),
array( 'db' => 'email',  'dt' => 'email' ),
array( 'db' => 'id_contrib', 'dt' => 'id' )

);

How can i put inside hidden field the value ' "data": "id" ' ?
