I have a custom text area component which displays remaining character count.
`
<div class=my-textarea>
<textarea>
{{content}}
</textarea>
{{#if isCharLimited}}
<span>
{{remainingCount}} left
</span>
{{/if}}
</div>
` Since textarea supports readonly and disabled attributes I want to use attribute bindings property to bind my attributes to textarea. How can I achieve this?
