AngularJS expressions not working in <img-crop>

[btyroque]

Hi, I am trying to modify the project for allowing crop multiple images in the same page, but I do not know how many images I would need, this is created dynamically. So, I need to associate to the 'image' field of a dynamic value, and at the same time I put this variable in my scope. The problem is that this label is not evaluating the angular code.

<div class="cropArea" id="{{'person'+person.Id}}">
    <img-crop image="{{'person'+person.Id}}" result-image="myCroppedImage"></img-crop>
</div>

Even when they have the same code, when the page is loaded the html code shows:

<div class="cropArea" id="person12345">
    <img-crop image="{{'person'+person.Id}}" result-image="myCroppedImage"></img-crop>
</div>

In my scope since the beginning the variable $scope.person12345 is created, but It is impossible to make the binding without this part.
What can I do?
