You need to enable Kotlin Android Extentions by adding this to your build.gradle:

apply plugin: 'org.jetbrains.kotlin.android.extensions'
androidExtensions {
    experimental = true
}

Since this new version of Kotlin, the Android Extensions have incorporated some new interesting features: caches in any class (which interestingly includes ViewHolder)

Using it on a ViewHolder (or any custom class). Note that this class should implement LayoutContainer interface:

class ViewHolder(override val containerView: View) : RecyclerView.ViewHolder(containerView), 
        LayoutContainer {

    fun bind(title: String) {
        itemTitle.text = "Hello Kotlin!"
    }
}
