_super Not Working the Way I Expect

_super Not Working the Way I Expect

I have created a few jQuery UI Widgets.  I noticed that when I try to change an option after the widget is created, it is not working correctly.  

Here is what my _setOption syntax looks like:
  1. _setOption: function (key, value) {
  2.             this._super('_setOption', key, value );
  3. }
Of course, I do use a switch statement to run any special code as needed depending on what option is being changed.

Here is my syntax to change an option:
  1. $('.ui-mywidget').cform('option', 'myOption', 'newValue'); 
Instead of changing 'myOption' it just adds an option called '_setOption' and the value is 'myOption'.  If I change the super call to this._super(key, value) it changes the option as expected.  What am I doing wrong here?

I am using jQuery 1.9.1.  It also happens with 1.9.2.
