onpaste calling a function javascript/jQuery

Question

I am trying to call a function when something is pasted into a field. Because I am using ext.net, I can not hardcode the function into the onpaste. This is why I am setting it from js.

$('#HtmlEditorFDEdit-inputCmp-iframeEl').contents().find("body").attr("onpaste", "alert('you pasted');");

This works, however I would like to call a function myFunction instead of alerting.

The following gives me a Uncaught ReferenceError: myFunction is not defined

$('#HtmlEditorFDEdit-inputCmp-iframeEl').contents().find("body").attr("onpaste", "myFunction();");

I tried moving the function around; from the bottom to the top of the external js file.

I am not even able to the following; (text is blank)

var text="asd";
$('#HtmlEditorFDEdit-inputCmp-iframeEl').contents().find("body").attr("onpaste", "alert(text);");

Any ideas as to what is going wrong?

Thank you!
