Vue.Js, binding a value to a checkbox in a component

I'm making a component which is a wrapper around a checkbox (I've done similar with inputs of type 'text' and 'number') but I cannot get my passed in value to bind correctly.

My component is:

<template>
  <div class="field">
    <label :for="name" class="label">
      
    </label>
    <div class="control">
      <input :id="name" :name="name" type="checkbox" class="control" :checked="value" v-on="listeners" />
    </div>
    <p v-show="this.hasErrors" class="help has-text-danger">
      <ul>
        <li v-for="error in errors" :key="error"></li>
      </ul>
    </p>
  </div>
</template>
<script>
export default {
  name: 'check-edit',
  props: {
    value: {
      type: Boolean,
      default: false
    },
    label: {
      type: String,
      default: ''
    },
    name: {
      type: String,
      default: ''
    },
    errors: {
      type: Array,
      default: () => []
    }
  },
  mounted () {
  },
  computed: {
    listeners () {
      return {
        // Pass all component listeners directly to input
        ...this.$listeners,
        // Override input listener to work with v-model
        input: event => this.$emit('input', event.target.value)
      }
    },
    hasErrors () {
      return this.errors.length > 0
    }
  },
}
</script>

I've imported it globally; and am invoking it in another view by doing:

<check-edit name="ShowInCalendar" v-model="model.ShowInCalendar" label="Show in calendar?" :errors="this.errors.ShowInCalendar"></check-edit>

My model is in data and the property ShowInCalendar is a boolean and in my test case is true. So when I view the page the box is checked. Using the Vue tools in firefox I can see the model.ShowInCalendar is true, and the box is checked. However, when I click it the box remains checked and the value of ShowInCalendar changes to 'on', then changes thereafter do not change the value of ShowInCalendar.

I found this example here: https://jsfiddle.net/robertkern/oovb8ym7/ and have tried to implement a local data property for it but the result is not working.

The crux of what I'm trying to do is have the initial checkstate of the checkbox be that of ShowInCalendar (or whatever property is bound via v-model on the component) and then have that property be update (to be true or false) when the checkbox is checked.

Can anyone offer me any advice please?

Thank you.
