Angular dom sanitize not working correctly

I used angular dom sanitizer to get html from a text area. It works perfectly for the first time after rendering the whole project, but the second time after revisit the component I got this message:

SafeValue must use [property]=binding: My text (see http://g.co/ng/security#xss).

I already pass the content with property binding using the inner-html property

const desc=this.sanitizer.bypassSecurityTrustHtml(this.ticket.description);
this.ticket.description = desc;
<p class="desc" [innerHTML]="ticket.description"></p>

I expected my plain text but i got that output described above.
