You could do with oninput event.

function manage(txt) {
  var bt = document.getElementById('btSubmit');
  if (txt.value != '') {
    bt.disabled = false;
  } else {
    bt.disabled = true;
  }
}
<input type="text" id="txt" oninput="manage(this)" />
<input type="submit" id="btSubmit" disabled />

In that case you need to use onpaste event.

document.getElementById("txt").onpaste = manage;

function manage(txt) {
        var bt = document.getElementById('btSubmit');
        if (txt.value != '') {
            bt.disabled = false;
        }
        else {
            bt.disabled = true;
        }
    }
<input type="text" id="txt" onkeyup="manage(this)" />
    <input type="submit" id="btSubmit" disabled />
