What does ampersand between functions mean in Scala

Question

I've encountered a strange piece of syntax in Scala, could someone explain it to me what does ampersand mean when aplied bettween functions that are passed as argument to other function?

partialUpdate {
    SetHtml(currentAmountId,
    Text(leadingBid.toString)) &
    SetHtml(nextAmountId,
    Text(minimumBid.toString)) &
    SetHtml(winningCustomerId, winningCustomer) &
    SetValueAndFocus(amountId,"")
}

Thank you for explaining this one to me.

& is a method on JsCmd in the Lift framework that concatenates two commands. It won't work on normal Scala strings.
