Custom Component With Slots

[twofivelabs]

I have my custom component working, but when I try to use the 'slots' within it doesn't work. I'm not entirely sure if there are some custom variables at play causing some challenges.

Vue.component('v-plainText', () => import('./../../components/Form/vPlainText.vue') )

Inside of form

<v-form-base>
   <template #slot-plain-text="{obj}">
       Using Slot
    </template>
</v-form-base>

<slot name="slot-plain-text" v-bind="{ obj }">
      Inside my custom component << This will show when rendering my custom component
</slot>

This does not work. is there a specific way to call custom slots?
