Cordova Android Banner is displayed twice , 3 , 4 ...

Hello, i use android 10.1.1 SDK30 CORDOVA CLI 11

when i refresh page index.html every time is create a new banner and keep the last one like the picture or open a new page like index2.html and back to index.html :

and when i use :

  banner.on('impression', async (evt) => {
    await banner.hide()
  })

the banner is not showing ,

my code :

let banner

var app= {
  initialize: function() {

    document.addEventListener('deviceready', async () => {
        await admob.start()
  	    banner = new admob.BannerAd({
            adUnitId: BannerID,
            size: 'SMART_BANNER'
        })

	//when added this function is hide banner and nothing is showing	
	banner.on('impression', async (evt) => {
            await banner.hide()
        })
        
        await banner.show()

  }, false);

    this.bindEvents();
  },

  bindEvents: function() {
      document.addEventListener('deviceready', this.onDeviceReady, false);
  },

  onDeviceReady: function() {

  bindEvents: function() {
      document.addEventListener('deviceready', this.onDeviceReady, false);
  },

  onDeviceReady: function() {
      app.receivedEvent('deviceready');

  },


var refreshPage = async() => {
     //hide the banner before refreshing the page
      await banner.hide();
      //refresh the page this way or any other way you prefer
      location.reload();
}
//call this when you refresh the page
//await refreshPage();
