title: Highcharts custom export hidding on Reset
body: <p>I am facing one issue with the highcharts.</p>
  
  <p>I have this code which renders the custom download instead of highcharts default print and download :</p>
  
  <pre><code>    $('#container').highcharts({
      exporting: {
                              buttons: {
                                  contextButton: {
                                      enabled: false
                                  },
                                  exportButton: {
                                      text: 'Download',
                                      y:30,
                                      //x: 1,
                                      //y: 5,
                                      // Use only the download related menu items from the default context button
                                      menuItems: Highcharts.getOptions().exporting.buttons.contextButton.menuItems.splice(2)
                                  },
                                  printButton: {
                                      text: 'Print',
                                      y: 30,
                                      onclick: function () {
                                          this.print();
                                      }
                                  }
                              }
                          }
         });
  </code></pre>
  
  <p>This code is working fine when I call it once, but when I call it again without refreshing the page, the download button does not show me all the options such as download as pdf, download as image etc.</p>
  
  <p>Any help?</p>
  
  <p>Thanks.</p>
