Bootstrap-Switch options don't take effect

I'm using Bootstrap-Switch and the documentation says that options can be passed as an object on initialization. enter link description here And here is a list of options: enter link description here So my code looks like this: ``` var options = { onText: "Yes", onColor: 'primary', offColor: 'danger', offText: "No", animate: true, }; $("[name='radioGroup1']").bootstrapSwitch(options); ``` And it all switch works fine, but none of the defaults are overwritten by the options. Anybody got any examples of how this might work?
