Computed Property fails to set input to a maximum

application.controller.js

import Ember from 'ember';

export default Ember.Controller.extend({
  myProperty: 1,
  myPropertyComputed: Ember.computed('myProperty', {
    get(key) {
      return this.get('myProperty');
    },

    set(key, value) {
      if (value > 2) {
        value = 2;
      } else if (value < 0) {
        value = 0;
      }

      this.set('myProperty', value);

      return value;
    }
  })
});

application.template.hbs

<p>On pressing the "increment" button, the input will stop from incrementing past the maximum, 2, only once. The input then continues to increment, even though the setter in the computed property sets the backing property and returned value to 2.</p>

{{input type="number" min=0 value=myPropertyComputed}}
