Update slider label or put title to left of slider

I am trying to update my slider label, but it wont update. Alternatively, is there a way to place the title of the slider to the left (in the label position)?

I’ve made an example to show what my issue is: https://snippet.webix.com/9f51cywg

Hello,

Please, use render() instead of refresh(). And everything will work well.
