how to remove back button on button click?

I am trying to move one page to to another using $state.go function. I am able to do that, but when the user clicks on the button, it creates a back button on next page. I don't want this when the user clicks on this main screen button.

I will explain again I have one button on main screen. On click I go to another screen, after I move it, it shows the back button on top header. I don't want this, but after that, if the user click moves to any page, it shows the back button. I don't want the navigation back button on the first screen. After that, I want here is my code (http://plnkr.co/edit/J4XI8hjCgvIUeVV89kYG?p=preview)

.controller('a', function($scope, $stateParams,$state) {

  $scope.moveto=function(){
    alert('--')
    $state.go('app.playlists')

  }

})

Use the hide-back-button attribute

<ion-view title="Playlists" hide-back-button="{{hideBackButton}}">

.controller('PlaylistsCtrl', function($scope) {
  ...
  $scope.hideBackButton = true;
})

See http://plnkr.co/edit/vIhljr0kdNB8u0rWWwCw?p=preview

use ionicHistory before calling $state.go('app.playlists')

Try like this

.controller('a', function($scope, $stateParams,$state,$ionicHistory) {

  $scope.moveto=function(){
    alert('--')
    $ionicHistory.nextViewOptions({
    disableBack: true
  });
    $state.go('app.playlists')

  }

})
