Im trying to get the id from a row of my table and pass it as parameter to my component <ModalExcluirAluno />, but it return undefined.

var usu;

{
        Header: 'Action',
            accessor: 'action',
            Cell: row => (
            <div onClick={() => adicionarValor(row.row.original.id)} >
               <ModalExcluirAluno value={usu} />
            </div>
        ),
},

function adicionarValor(id) {
    usu = id;
    console.log(usu)
}

In my console it return the id normaly, but to my function it gave me "undefined", I know thats why my function dont change the variable value, even so, i want to pass to the id value of the row clicked to my component, what can i do?
