Dynamically render component

Hello. For example, user can type something like that: “hello @someUser”.
Then throw markdown helper @someUser transofrom to
<a class='meniton' href='/users/someuser'>someUser</a>, like discuss or twitter.
How i can replace mention link with {{user-mention-comp}}? i want to handle hover and click actions.
Can i use didInsertElement hook in parent component and replace all links?
