Problem with Customize ToolBox

Hello
 
I'm having trouble with the toolbar when I customize it incluiding a new item.
When you first create the component, the beforetoolbarcreated event is executed, but if I try to create the component again the beforetoolbarcreated event does not run.
 
I created a function to create the component. In my page I have a list of options, and when the user selects the option, I go through the parameter for this function, and it creates the component

var pivot;

var createCube = function(options) 
{
    pivot = $("#pivotContainer").flexmonster({
             componentFolder: "/Content/js/flexmonster/",
             global: {
                  localization: "loc/pr.json"
             },
             toolbar: true,
             beforetoolbarcreated: customizeToolbar
             , licenseKey: ""
     });

     pivot.setReport(options);
 }

Below is the function that sends the options to create the component. A JSON object is sent which is the reportOptions generated by the getReport
 

var changeFlexMonster = function(opt)
{
    if (pivot != null) 
    { 
        pivot.dispose();
    }
  
    var cube = listCube.find(function(obj) {
                return obj.opt == opt 
             });

    createCube(cube.options);
}

I am attaching two images, one when you create the component for the first time, and the other when you create the component the second time.
