I simply want to populate a drop select based on what was selected in a 
previous drop select box I found a dajax/dajaxice method but it does not 
seem to trigger any clues please?

views.py

from dajax.core import Dajax
from dajaxice.decorators import dajaxice_register

@dajaxice_register
def updatecombo(request, option):
    dajax = Dajax()
    options = TopicChoices.objects.all().filter(theme=option)
    out = []
#    for option in options[int(option)]:
    for opt in options:
        out.append("<option value='#'>%s</option>" % opt)
    dajax.assign('#combo2', 'innerHTML', ''.join(out))
    return dajax.json()


search.html
                <select onchange="Dajaxice.updatecombo(Dajax.process, 
{'option':this.value})" size="1"><option value="">Please select</option>
                    {% for x in form.adv_choices %}
                        <option value="{{ x.id }}"{% ifequal x.id 
selected_adv %} selected="selected"{% endifequal %}>{{ x.title }}</option>
                    {% endfor %}
                    </select>
                    <select id="combo2" onchange="" size="1"></select>
                <div style="background-color:#50593B; margin-top: 0px; 
padding:20px 0px; ">

I don't get any errors just no population of "combo2"
