Tooltip on input breaks 2 way binding

If I place a tooltip on an input then the 2 way binding from input to controller does not work.

Here I have created a plunker which hopefully illustrates this issue:

@markg66 This is a scope issue, because tooltip is creating an isolated scope. Always use the dot rule.
