Set Angular checkbox repeat from outside controller

I am trying to simplify my controller. So I tried to set variable to populate my checkbox list from outside controller. Is it possible?

Here is my current code http://ift.tt/2gSgJa0

VIEW HTML

<div ng-controller="AdminEventsCtrl">
  <h1>Array 1</h1>
  <ul>
    <li ng-repeat="item in array1">
      <input type="checkbox" ng-model="formData.value1[item.value]" value="" />
      
    </li>
  </ul>

  <h1>Array 2</h1>
  <script>
    array2 = [{
    text: 'Option 1',
    value: 'opt1'
  }, {
    text: 'Option 2',
    value: 'opt2'
  }, {
    text: 'Option 3',
    value: 'opt3'
  }, {
    text: 'Option 4',
    value: 'opt4'
  }];
  </script>
  <ul>
    <li ng-repeat="item in array2">
      <input type="checkbox" ng-model="formData.value1[item.value]" value="" />
      
    </li>
  </ul>

  <pre>Array1= </pre>
  <pre>Array2= </pre>
</div>

SCRIPT JS

var myApp = angular.module('myApp', []);

function AdminEventsCtrl($scope) {
  $scope.formData = {};

  $scope.array1 = [{
    text: 'Option 1',
    value: 'opt1'
  }, {
    text: 'Option 2',
    value: 'opt2'
  }, {
    text: 'Option 3',
    value: 'opt3'
  }, {
    text: 'Option 4',
    value: 'opt4'
  }];
}
