How to set a different value to a variable in the form at the time of rendering

this is my code....

{% for element in form %}
            {% if is_a(element, 'Phalcon\Forms\Element\Hidden') %}
                {{ element }}
            {% else %}
                <div class="form-group">

{% if element.getName() == "name" %}

                    {{ element.label() }}
                    {{ toedit.type_name }}

{% else %}

                    {{ element.label() }}
                    {{ element.render(['class': 'form-control']) }}
{% endif %}

                </div>
            {% endif %}

when the element.getName()=="name"; i want to set different value in the form rather than rendering it.......how to do this????
