Using Javascript to catch typing in text box

I got it working!  I used a single Javascript that executes when the timeline starts:

const Inputs = () => {
  var myInputs = document.querySelectorAll('input[type="text"]');


  myInputs.forEach(function(input, index) {
    input.addEventListener('keyup', function(event) {

      var str = input.value;
var player = GetPlayer();


  //Create a RegExp object using the constructor  
  let regex = new RegExp(str);

 let text = "Item L2";
  
//  Test if the regex matches the text
 let searchGood = regex.test(text);

  player.SetVar("Correct_Value", searchGood);
   player.SetVar("TextEntry44", str);
    });
  });
};

setTimeout(Inputs, 100);

Then, I had the remaining triggers set to "when TextEntry44 changes"
