[slider] unexpected result on value initialization in javascript

[foutesting]

Bug Report

Hello,
When I try to initialize the slider cursor with a number (eg 5000) in javascript with the Behaviors : set value(value), it doesn't work.
Result: the slider goes to its maximum and there is a scale change.

Steps to reproduce

1. HTML

2. JAVASCRIPT
   $('.ui.slider.gaz')
   .slider(
   'set value', '5000',
   {
   min: 0,
   max: 30000,
   start: 250,
   step: 250,
   smooth: true,
   onChange: function(value) {
   $('#display-consogaz').html(value);
   document.getElementById("inp-consogaz").value = value;
   }
   })
   ;

Expected result

the right value with the right scale when loading the page

Before using behaviors like set value you have to initialize the slider first.
