Puck sending same key repeatedly?

Here's my current code. Previous versions did not have the "sending" check that this now does. I haven't experienced issues with this version of it.

console.log(NRF.getAddress());
console.log("Battery: " + E.getBattery() + " " + Puck.getBatteryPercentage());

var debugText = false;

var kb = require("ble_hid_keyboard");
NRF.setServices(undefined, { hid : kb.report });

var sending = 0;

function catchButton(e) {

  var keyDown = e.state === true;
  var keyUp = e.state === false;
  var click = false;

  debug_log(keyDown?"key down" : (keyUp? "keyUp" : "broke"));

  if(keyUp) {
    triggerCommand();
  }
}

function triggerCommand() {
  try {
    if(!sending) {
      sending = 1;
      digitalWrite(LED3,1);
      NRF.sendHIDReport([0,0,99,0,0,0,0,0], function() {
        NRF.sendHIDReport([0,0,0,0,0,0,0,0], function() {
          setTimeout(function() {
            console.log("press");
            digitalWrite(LED3,0);
            sending = 0;
          }, 250);
        });
      });
    }
  } catch (e) {
    console.log("caught:" + JSON.stringify(e));
    digitalWrite(LED3,0);
    digitalWrite(LED1,1);
    setTimeout(function() {
      digitalWrite(LED1,0);
      sending = 0;
    }, 250);
  }
}


setWatch(catchButton, BTN, {repeat:true, debounce:50, edge:'both' });

function debug_log(t) {
  if(debugText) console.log(t);
}
