Play Framework template not Html type

I have a template named mainBodywith the form:

@(title: String)(html: Html, moreScripts: Html = Html(""))

I can call it like

views.html.mainBody("All properties")(views.html.showProperties(list))

views.html.showProperties()- another template. I get the impression that templates are just functions that return Html. However, if I extend this to:

views.html.mainBody("All properties")(views.html.showProperties(list), views.html.showPropertiesScripts)

Where views.html.showPropertiesScriptsis just a template with some HTML code, I get an error:

play.PlayExceptions$CompilationException: Compilation error[type mismatch;
 found   : views.html.showPropertiesScripts.type
 required: play.twirl.api.Html]
        at play.PlayExceptions$CompilationException$.apply(PlayExceptions.scala:27) ~[na:na]

        at play.PlayReloader$$anon$1$$anonfun$play$PlayReloader$$anon$$taskFailureHandler$1.apply(PlayReloader.scala:229) ~[na:na]

I do not understand this. Instead of the expected type Html, views.html.showPropertiesScriptsis there views.html.showPropertiesScripts.type? What is it and why views.html.showPropertiesScriptsnot type Html(like my other templates)?
