How to restore the reactivity of the inner vue component?

Question

Vue.js

I am using one vue component in another.
Here is a call from one component to another:

<div>
    <ref-values :model="refModel"></ref-values>
  </div>

The inner component is a draggable field. When clicking on the delete button, the field was repainted. After embedding, the change only becomes visible after dragging the field.
I think the problem is reactivity.
