Unexpectedly when a checkbox has a .toggle() bound to it the state will not change after its callback function is completed. The state will change within the callback function but it will not be saved.

Example Code:

$("input").toggle(function(){
   console.log("A",this,this.checked)
},
function() {
   console.log("B",this,this.checked)
});

Output:

A <input type="checkbox"> true
B <input type="checkbox"> true

If this is intentional it should probably be documented.
