here i am loading select options with ajax and binding multiselect jsfiddle . Let me know if this helps you.

$(document).ready(function(e) {         
        var form_data = $("#frm").serialize();
        var form_url = $("#frm").attr("action");
        var form_method = $("#frm").attr("method").toUpperCase();

        $("#loadingimg").show();

        $.ajax({
            url: form_url, 
            type: form_method,      
            data: form_data,     
            cache: false,
            success: function(returnhtml){     
                alert('binded options to select on ajax success');
                $.when(assignOptions()).done(function(){
                  bind();
                });              
            }           
        });    
});

functionassignOptions(){
  $("#display_list").append('<option value="W1">VICccccc</option><option value="W2">NSW</option><option value="W6">TAS 3</option>');
}
functionbind(){    
  $("select").multiselect({
   click: function(event, ui){
      alert(ui.value + ' ' + (ui.checked ? 'checked' : 'unchecked') );

   },
   beforeopen: function(){
      $callback.text("Select about to be opened...");
   },
   open: function(){
      $callback.text("Select opened!");
   },
   beforeclose: function(){
      $callback.text("Select about to be closed...");
   },
   close: function(){
      $callback.text("Select closed!");
   },
   checkAll: function(){
      $callback.text("Check all clicked!");
   },
   uncheckAll: function(){
      $callback.text("Uncheck all clicked!");
   },
   optgrouptoggle: function(event, ui){
      var values = $.map(ui.inputs, function(checkbox){
         return checkbox.value;
      }).join(", ");

      alert("CheckboXES " + (ui.checked ? "checked" : "unchecked") + ": " + values);

   }
});
