Change inline SVG x and y with ecmascript

I am using inline SVG in SVG and set some default x and y values. When I change them, the inline SVG moves accordingly. I am trying to change it with

    var inlineSVG = document.getElementById("inlineSVG");
    inlineSVG.style.x = "90";

      

        
        
        
      

    

and adds style = "x: 90px;" but that doesn't actually affect the element. This is weird (in my head) because it works with rect , but not svg . Here is my actual code:

<?xml version='1.0' encoding='UTF-8'?> 
<svg width='1000' height='360'
 xmlns='http://www.w3.org/2000/svg'
 xmlns:xlink="http://www.w3.org/1999/xlink"
 onload='init(evt)'
 > 

<script type='text/ecmascript'>
function init(event){
    var wing1 = document.getElementById("wing1");
    wing1.style.x = "90";
}
</script>
