Can I debounce a checkbox input in Aurelia? - aurelia

Question

I'm trying to use the debounce binding behaviour on a list of checkboxes, but it doesn't seem to be working the way I expect (I'm not sure if you can even debounce a checkbox):
<label repeat.for="v of values">
<input type="checkbox" value.bind="v" checked.bind="checkedVal & debounce:1000"> Checkbox value "${v}"
</label>
clicking on any of the checkboxes results in the checkedVal array updating immediately, whereas it works as I expect for a normal input:
<input type="text" value.bind="textVal & debounce:1000"/>
Can I debounce a checkbox input?
Here's the full code, with a GistRun here.
app.html:
<template>
<h1>Checkbox bind debounce</h1>
<form>
<label for="text">text input with debounce:1000 </label>
<input type="text" value.bind="textVal & debounce:1000"/>
<div repeat.for="v of values">
<br/>
<label>
<input type="checkbox" value.bind="v" checked.bind="checkedVal & debounce:1000"> Checkbox value "${v}"
</label>
</div>
</form>
<br/>
<p>Text value: ${textVal}</p>
<p>Checked values:</p>
<p repeat.for="v of checkedVal">${v}</p>
</template>
app.js:
export class App {
values = [1, 2, 3];
checkedVal = [];
}
Thanks!

At this time, it's not supported. The debounce binding behavior controls the rate at which the checkedVal property is assigned. In a checked binding, the property isn't assigned, the array instance referenced by the property is mutated with push and splice which circumvents the debouncing in the binding expression.
