unable to define individual position

Plunkr demo here: http://plnkr.co/edit/VFcfYRe8jY53Mkup6UeK?p=preview

the issue is my inability to dynamically define where the notification will appear. Passing in different numbers for the "startTop" and "startRight" parameters do not affect where the notification appears (as seen in the plunkr example. In my application I need to make the notification appear in different places (to correspond with specific elements) but can not define the position through these (startTop, startRight) parameters. Simply using "positionX: 'center'" is not specific enough of a position.

All of them show on the same place.

Same here, I think the issue is you're using an assignment operator(=) where you maybe meant to use a conditional operator(==) in this line: https://github.com/alexcrack/angular-ui-notification/blob/master/src/angular-ui-notification.js#L85

What is the solution?
I have the same problem.
The notification appears in the same place despite I had defined the 'positionY' and 'positionX'.
