Hidden inputs do not work for objects

Hello,

"_el.attr('value', scope.$eval(_el.attr('ng-model')));" (line 157)

This seems to only work if the ng-model is not an object or of some other complex structure. I wanted to give it a token (as object), but it kept converting it to [object Object]. (I tried stringifying it and stuff, it seems to not be a real object. Serversided I cannot read it as well.)

According to the docu it only allows a String or Number: http://api.jquery.com/attr/#attr2
Which is quite confusing because you can actually set the directive "value" to an object manually..
