Error re-creating component

Hello!
I'm having problems with flexmonster when creating a new pivot.
In my preview screen I have the following process:
When the user enters the view screen, I create an instance of flexmonster and inform the options.

var pivot = null;

var createCube = function(options, reload) 
{
    //check if exists instance of pivot
    if (pivot) 
    {
        flexmonster.clear();
    }

    //check if exists an intance of pivot or is reload operation
    if (!pivot || reload) 
    {
           pivot = $("#pivotContainer").flexmonster({
           componentFolder: "/Content/js/flexmonster/",
           global: {
                        localization: "loc/pr.json"
                   },
           toolbar: true,
           beforetoolbarcreated: customizeToolbar,
           licenseKey: "@ConfigurationManager.AppSettings["flexMonsterKey"]"
           });
    }

     pivot.setReport(options);
}

//create cube first time
createCube(options,false);

But, i have an process for reload the records in pivot, that executes the function createCube again.
 

$("#buttonReload").on("click",fuction(e) 
{
     //call function, but send true for reload data;
     createCube(options,true);
});

As I am reporting the reload value as true, the following code will be executed:

flexmonster.clear() ;

pivot = $("#pivotContainer").flexmonster({
           componentFolder: "/Content/js/flexmonster/",
           global: {
                        localization: "loc/pr.json"
                   },
           toolbar: true,
           beforetoolbarcreated: customizeToolbar,
           licenseKey: "@ConfigurationManager.AppSettings["flexMonsterKey"]"
           });

The pivot loads smoothly, but the menu options no longer work, and begin to display the following error in the console:
Uncaught TypeError: Cannot read property 'getOptions' of null
