css - Customize Bootstrap checkboxes

I'm using Bootstrap in my Angular application and all other styles are working like they should, but checkbox style doesn't. It just look like plain old checkbox.

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">
<div class="container">
  <form class="form-signin">
    <h2 class="form-signin-heading">Please log in</h2>
    <label for="inputEmail" class="sr-only">User name</label>
    <input [(ngModel)]="loginUser.Username" type="username" name="username" id="inputEmail" class="form-control" placeholder="User name" required autofocus>
    <label for="inputPassword" class="sr-only">Password</label>
    <input [(ngModel)]="loginUser.Password" type="password" name="password" id="inputPassword" class="form-control" placeholder="Password" required>
    <a *ngIf="register == false" (click)="registerState()">Register</a>
    <div class="checkbox">
      <label>
         <input type="checkbox" [(ngModel)]="rememberMe" name="rememberme"> Remember me
         </label>
    </div>
    <button *ngIf="register == false" (click)="login()" class="btn btn-lg btn-primary btn-block" type="submit">Log in</button>
  </form>
</div>

Since Bootstrap 3 doesn't have a style for checkboxes I found a custom made that goes really well with Bootstrap style.

Checkboxes

.checkbox label:after {
  content: '';
  display: table;
  clear: both;
}

.checkbox .cr {
  position: relative;
  display: inline-block;
  border: 1px solid #a9a9a9;
  border-radius: .25em;
  width: 1.3em;
  height: 1.3em;
  float: left;
  margin-right: .5em;
}

.checkbox .cr .cr-icon {
  position: absolute;
  font-size: .8em;
  line-height: 0;
  top: 50%;
  left: 15%;
}

.checkbox label input[type="checkbox"] {
  display: none;
}

.checkbox label input[type="checkbox"]+.cr>.cr-icon {
  opacity: 0;
}

.checkbox label input[type="checkbox"]:checked+.cr>.cr-icon {
  opacity: 1;
}

.checkbox label input[type="checkbox"]:disabled+.cr {
  opacity: .5;
}
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">

<!-- Default checkbox -->
<div class="checkbox">
  <label>
   <input type="checkbox" value="">
   <span class="cr"><i class="cr-icon glyphicon glyphicon-ok"></i></span>
   Option one
   </label>
</div>

<!-- Checked checkbox -->
<div class="checkbox">
  <label>
   <input type="checkbox" value="" checked>
   <span class="cr"><i class="cr-icon glyphicon glyphicon-ok"></i></span>
   Option two is checked by default
   </label>
</div>

<!-- Disabled checkbox -->
<div class="checkbox disabled">
  <label>
   <input type="checkbox" value="" disabled>
   <span class="cr"><i class="cr-icon glyphicon glyphicon-ok"></i></span>
   Option three is disabled
   </label>
</div>
