bootstrap-datetimepicker with vue.js not working properly

I am trying to use bootstrap-datepicker with Vue.js Trying to create a simple datepicker component. The problem is, when I write into input, component's data is updated. But when I use datepicker gui, it doesn't work. Data is not updated. Why? What is missing exactly?

Here is my code:

Vue.component('picker', {
  'props': {
    'date': {
      'twoWay': true
    }
  },
  'template': '\
      <div class="form-group">\
          <div class="input-group date datepicker">\
              <input type="text" class="form-control" v-bind:value="this.date">\
              <span class="input-group-addon">\
                  <span class="glyphicon glyphicon-calendar"></span>\
              </span>\
          </div>\
      </div>',
  'watch': {
    'date': function(value) {
      console.log('Updated!');
    }
  },
  'mounted': function() {
    $(this.$el.firstChild).datetimepicker();
  }
});

app = new Vue({
  'el': '#app',
  'data': {}
});

Solution

I couldn't find a better way than losing focus (blur).

Here's my code:

Vue.component('picker', {
    'props': ['date'],
    'template': '\
        <div class="form-group">\
            <div class="input-group date datepicker">\
                <input type="text" class="form-control" :value="this.date" v-on:focus="datepick_dialog_open" v-on:blur="select_by_lose_focus">\
                <span class="input-group-addon">\
                    <span class="glyphicon glyphicon-calendar"></span>\
                </span>\
            </div>\
        </div>',
    'mounted': function() {
        $(this.$el.firstChild).datetimepicker();
    },
    'methods': {
        'datepick_dialog_open': function() {
            this.$el.firstChild.children[1].click();
        },
        'select_by_lose_focus': function() {
            console.log('AHOY!');
            this.date = this.$el.firstChild.firstChild.value;
        }
    }
});

app = new Vue({
    'el': '#app',
    'data': {}
});

The point is, you really can't use it if your element does not lose focus. It updates the data when input loses its focus. IDK any better way.

v-on:focus is irrelevant. It just opens the datetime picker UI when input gains focus.

The main job is done by select_by_lose_focus.
