carabiner library with smarty

[eluser]steven dobbelaere[/eluser]
I'm trying to use the carabiner asset manager in my codigniter cms but I use smarty.
I placed the $this->carabiner->display() function in my controller but it echo's rather then
return a value. So because I use the function in my controller instead of the view it places
the css and javascript code at the beginning of my html output.
Assigning it to a smarty variable doens't work because it echo's the output.
Inline php code in a smarty template doesn't work either.
Any ideas how to solve this?
