jsTree - Call function when checkbox is ticket and get all ticked checkboxes

Question

Is there a way to call a function whenever a checkbox is ticked in jstree? I have the following example and would like to call the function "getImages" whenever a checkbox in the tree is ticked plus I want to collect all ticked checkboxes inside this function. Any idea how to do this?

$('#container').jstree({
    "core": {
      "themes":{ "icons":false },
		  'data' : [
      {
        "text" : "Root",
        "children" : [          
          { "id": 1, "text" : "Item A", "state" : { "opened" : true }, "children" : [ { "id": 11, "text" : "A-1"}, { "id": 12, "text" : "A-2"} ] },
          { "id": 2, "text" : "Item B" }
        ]
      }
    ]    
    },
    "checkbox" : {
      "keep_selected_style" : false
    },
    "plugins" : [ "checkbox", "wholerow" ]
  }
).on('ready.jstree', function(){ $(this).jstree('open_all') });

function getImages() {
  // get all the id of all ticked checkboxes
}

My own Test:

$(function () {


$('#container').jstree({
    "core": {
      "themes":{ "icons":false },
		  'data' : [
      {
        "text" : "Root",
        "children" : [          
          { "text" : "Item A", "state" : { "opened" : true }, "children" : [ "A-1", "A-2" ] },
          { "text" : "Item B" }
        ]
      }
    ]    
    },
    "checkbox" : {
      "keep_selected_style" : false
    },
    "plugins" : [ "checkbox", "wholerow" ]
  }
).on('ready.jstree', function(){ $(this).jstree('open_all') });

function getImages() {
  console.log('ok');
}

     $("#container").bind("changed.jstree",
    function (e, data) {
        //alert("Checked: " + data.node.id);
        getImages(); 
        //alert(JSON.stringify(data));
    });


});
