Creating the element with the directive
The framework's compiler walks through the DOM, looking for elements that match
the directives. In the following code is our directive before being compiled:

After this, the element is compiled by the $compile service, returning the link
function of the directive. At this moment, the template is already generated,
however, we still need to call the link function, passing the $scope object in order

{{topic}}
Calling the link function with the scope

{{topic}}
Please inform the plate and the color of the car
