IONIC on IE9 not working

Hi all

I’ve someone please could provide some workaround for this one?
If I run my IONIC application in IE9, i’m getting the error back:

Unable to get value of the property ‘indexOf’: object is null or undefined
ionic.bundle.min.js, line 6, character 31181.

When viewing the JS file. The exact line is:
var o=t.CSS.TRANSITION.indexOf(‘webkit’);

Did somebody encountered this problem? Or has a fix for it?

I know that IONIC is meant for hybrid mobile dev, but I really need to get this working on IE9 also…

Thanks in advance
