JQGrid Sort Icon not showing in IE

I fixed Sort Icon Bug for IE

Its sounds funny but whenever we apply , guiStyle: 'bootstrap' to JQGrid, its overwriting other styles

I applied similar to client but removed all styles under custom

$.jgrid.guiStyles.bootstrapcustom = {

         baseGuiStyle: "bootstrap"

     };

And bind to JQGrid as , guiStyle: 'bootstrapcustom' below screenshot, if you have any queries let me know
