[removed] Creating a persistently bound function

Question

I realise a question like this is asked pretty frequently (I\'ve probably read every one of them over the past few days trying to understand how to fix this) - but in this case,

You simple wrap the call to aFoo.sendData in an anonymous function:

aBar.getSomething(data, function () {
    aFoo.sendData();
});

Because your referencing aFoo.sendData, the reference to this inside sendData is no longer aFoo. When using the anonymous function, you're not referencing the function; you're simply invoking it as a method on the aFoo instance, so this is still aFoo.
