Contact me inside collapsible node not working

[Method-Development]

Fiddle showing issue:
http://jsfiddle.net/mjg34s1h/

I have this node:

` dqLink = {
parent: complaintFiled,
text:{
title: "MTD",
contact: {
val: "contact me",
href: "http://twitter.com/",
target: "_blank"
}
},

	collapsable: true,
	collapsed: true
	
}`

and when I click on the node it expands the child nodes associated with it but if I click on the "contact me" it does not open the link in a new window. Any suggestions?
