Defining triggers event parameter with dynamic value

Trying to define a dynamic parameter to ‘click triggers’ on a UI page…and it doesn’t like the syntax…
remove($event,{{this.businessObjectName + 'Link'}})

Dave says:
The right side of a “triggers” item is code so it needs to be a valid function call. The “{{}}” syntax is not code. That is string interpolation that lets you parametrize a string. So the right syntax here is:
remove($event,businessObjectName + ‘Link’)
“this” is not required because this expression is in the template. “this” is only required inside a method.
