Run a function inside a template node using msg.payload

I have a progress bar with html, css and javascript code which I have written inside a template node (for dashboard). I have understand that I can display some text dynamically (coming from a msg.payload) using {{msg.payload}} but I do not get how to launch a function using my msg.payload.

So in my example, I'd like to run my function move() which is actually run when someone click the html button using my msg.payload. So I will have a button node, when clicked will run the move() function of my template node...

Thank you for your help

But it is working like you described, isn't it ? Perhaps you want some other behaviour ?

Yes I'd like to be able to run the code with a node button (not with the html button), so I will have a payload to run the move() function...
