How to re-run dom-repeat with sorting when changing the bool property in a Polymer element

Question

How can I repeat the sorting and rendering of an element when something has changed in my element or when I want from code or automatically? Thanks you

<template is="dom-repeat" items="[[attachments]]" as="attach_item" sort="_sortItems"></template>

You need to set an observer for the fields you want to view.

Quoted from polymer documents:

By default, filtering and sorting functions are performed only when the array itself is mutated (for example, by adding or removing elements).

:

<template is="dom-repeat" items="{{employees}}"
filter="isEngineer" observe="type manager.type">

PS: , this.set( "array.index.field", ),
