I am calling this "display" function in Vue.js, which loads an image. I am using img.onload in order to verify when the image has completed its loading. However, the code never reaches the console.log line. What am I missing?

<input type="button" name="display" value="Display" v-on:click="display" />

display () {
  var img = new Image()
  img.onload = function () {
    console.log('Loaded')
  }
  img.src = '../Image.jpg'
}

Thank you. J
