Basemap selected doesn't Update - Mobile Version

[WestonSF]

The basemap selected won't update in the mobile version for some reason. The below code should kick in when the theme is changed to update the selected basemap in the ArcGIS Online web map.

// Set the radio button - Mobile version - NOT WORKING FOR SOME REASON!!!
if (currentPage.indexOf("mobile") != -1) {
$("#" + this.id).prop("checked", true)
}
