I had to handle this just yesterday; I ended up using setTimeout() to
make it work.
In my case, I have a login form view that is intended to be as
portable as possible. It allows the including page to perform its own
actions after the login is successfully completed. To accomplish
this, it executes a loginComplete() method that is supposed to be set
by its parent page. My quandary as it relates to you is that I can't
override loginComplete() until it exists!
So, loginform.js has a LoginForm namespace with the loginComplete()
function:
var LoginForm = { //page namespace
username: function() {
return $('#loginform_user').val();
},
loginComplete: function() { //override by parent page
alert('login OK');
}
}
// this should be moved into the LoginForm namespace...
function loginSuccess(responseText, statusText) {
if (responseText == 'OK') {
LoginForm.loginComplete();
}
}
----
While main.js loads and overrides the login completion method:
//$div = jQuery(div where the login form resides);
$div.load('auth/loginform', {}, function(){
//once the loginform's scripts have been evaluated,
//set its event listener
(function setlistener() {
if (typeof LoginForm == 'undefined') {
//recurse until LoginForm is available, i.e. script
evaluated
setTimeout(setlistener, 10); //wait 10 ms before
trying again
} else {
LoginForm.loginComplete = function() {
$main.before($loaddiv); //show loading spinner
$div.hide('slow'); //hide login form
$main.load('http://localhost/wdm/home/wdmhome',
{}, function() {
$loaddiv.remove();
});
}
}
})(); //immediately execute setlistener()
});

I edited out a bunch of additional text; hopefully the gist remains
and is useful.
