checkboxradio is not a function

checkboxradio is not a function

I am using jquery 1.9.1, jquery mobile 1.3.1 (js & css) in my web app. When i call checkboxradio to uncheck all the check boxes, its throwing the exception "checkboxradio is not a function"

 $("input[type='checkbox']").attr("checked",false).checkboxradio("refresh");

When i try the same as a sample app, it works.

The problem is : the function inside jquery mobile 1.3.1.js file is not getting called. I do see the jquery mobile 1.3.1.js in the scripts loaded in firebug.

Please advise on how to find out whats going wrong here.

Thanks..
