How to set ion-searchbar placeholder dynamically

#1

I would like to have a generic search bar component but can’t figure out how to set the placeholder through binding or interpolation. Is this possible and if so how?

Found this -

Doesnt seem to work.

placeholder={{myVar}}
[placeholder]="myVar"

Also no luck.

I might have missed something simple but Ive looked around and cant figure it out.

Just needed to put a function in apparently

[placeholder]="getMyPlaceholder()"
