When checkbox is clicked, how to know the state of the checkboxes

I have a set of check boxes, and when one is clicked I need to return the values of the unchecked ones. HTML:

<div id="myCheckboxList">
<input type="checkbox" name="myList" value="1" checked>1
<input type="checkbox" name="myList" value="2" checked>2
<input type="checkbox" name="myList" value="3" checked>3
</div>

JavaScript:

$(function(){
  $("input[name=myList]").on("click",function(){
    console.log("triggered");
    //code here to find which ones are unchecked

  });
});

I have tried to also add this in the code

$boxes = $('input[name=myList]:not(:checked)');
$boxes.each(function(){
    // Do stuff with for each unchecked box
});

Unfortunatly the "triggered" in not getting output to console, so unsure why it is so, and how would i get an event to happen when the checkboxes are hit
