I think it may have something to do with setOnLoadCallback.
However, you can add a reference to the callback in the load statement.
$(document).ready(function(){
if ($("#myId").length > 0) {
google.load('visualization', '1', {
'packages': ['corechart'],
'callback': function(){
if ($("#myId").length > 0) {
alert("Found a match!!");
}else{
alert("Not found!!");
}
}
});
}
});
