Add SimpleCropper plugin to GC

Hello,

I am trying to add SimpleCropper plugin (https://github.com/tomazdragar/SimpleCropper) to Grocery Crud edit form but I have a problem, file browser doesn't open.

What I did is the following:

I load all the files necesary in the header.

<script src='....assets/backoffice/plugins/jquery-1.11.js'></script>
<script src='....assets/backoffice/js/jquery.Jcrop.js'></script>
<script src='....assets/backoffice/js/jquery.SimpleCropper.js'></script>

I initialize the plugin

<script>
   $('.cropme').simpleCropper();
</script>

In the controler function I use callback_edit_field to convert the input to the div I need.
```
$this->grocery_crud->callback_edit_field('portfolio_image', array($this, 'cropper'));
```
cropper function is:
```
function cropper() {
      $div = '<div class="cropme" style="width: 400px; height: 200px; position: relative;"></div>';
      return $div;
}
```
All seems to be ok, the files are loaded and the div is created but nothing happen, when I click on the div, the files browser is not opened. I have no error on firebug and I don't know why it does not work.

I imagine something is wrong with GC because this plugin is very simple to use but I don't know what.

Thank for help.
