Ember 2.11.X How to get the Input value of and component through the action handler

Problem: I want to transfer the changed value from the input-field component to the action, but i recieve only the initially value.

The controller holds the variable width with an initially of 100, but should update after the value changed in the input field.

        <form  class="form-inline waves-effect waves-light" style="width:50px">
                 
        </form>
