Enlace de funciones dinámicas de JavaScript/jQuery y ajax

I'm trying to build out a dynamic list of UI elements. I can hard code the UI list now, and everything works fine. I want this to be extensible however, so I'm trying to figure a way of passing id tags and corresponding functions to be called. Essentially, the callback function for my ajax call isn't being executed, though I am posting the correct data, and receiving the correct response. Here's the code:

myModule = function () {
  var titleUI = Object.create(ChainUI());
  var memcachedId = '<?php echo $memcachedId;?>';
  return {
    printChain: function(data) {
      alert("printchain");
      var territories = jQuery.parseJSON(data);
      titleUI.makeChainTable();
      territories.forEach(function(territory) {
        titleUI.territoryDisplay(territory);
      }); 
      titleUI.tableDecorator($('#chainTable'));
    },
    loadChain: function() {
      titleUI.destroyChainTable();
      var url = 'traffichandler.php';
      var instruction = {'instruction': 'titleChain', 'method': 'printChain', 'memcachedId': memcachedId.toString()};
      $.post(url, instruction, this.printChain);
    },
    loadDefault: function() {
      titleUI.loadUI(['Title Chain'], [this.loadChain]);
    }
  };
}();

The corresponding titleUI code follows:

var ChainUI = function() {
 return {
 loadUI: function(uiList, funcList) {
  $('#uiFunctions').empty();
  for(var i in uiList) {
    var toDom = '<li id="'+uiList[i]+'">';
    toDom += uiList[i];
    toDom += '</li>';
    $('#uiFunctions').html(toDom);
  }
  for(var i = 0; i < uiList.length; i++) {
    var myFunc = funcList[i];
    $('#uiFunctions').delegate($('#'+uiList[i]), "click",
      function() {myFunc();}
    );
  }
},

}

In myModule.loadDefault, I can get this.loadChain to fire. I can't get this.printChain inside the $.post to work though. If remove all the dynamic stuff this.printChain works no problem. Don't get too hung up on the syntax, as is, the syntax is fine on my end. How can I get the ajax call back to work? Thanks!
