<button type="button" id="btn">button</button>

or event delegation

function addbutton () {      var btn = document.createelement("button");      btn.type = "button";      var t = document.createtextnode("click me");      btn.appendchild(t);       document.body.appendchild(btn);  }    document.body.addeventlistener("click", function(e) {      if (e.target.tagname==="button") {  //i use class or data attribute instead of tagname        addbutton();      }  });

<button type="button" id="btn">button</button>
