Is the callback on jQuery's getScript() unreliable or am I doing something wrong?

Question

I\'m using the following bit of script to load another one:

$.getScript(\"CAGScript.js\", function () {
    try {
        CAGinit();
    } catch(err) {

I wanted to have something similar to auto_load in PHP implemented in JS, the typical solution is using try-catch on all functions.. when the function is missing we jump to downloading its library.. My solution is taken from Pieter solution as follows:

function CheckUserPW(username,password){
    try{
       loginCheckUserPW(username,password);
    } catch(err) {
        $.getScript('login.js', function(xhr){ 
            eval(xhr);
            loginCheckUserPW(username,password);
        });
    }
}
