jquery document ready aggregation

Hi! I would like to write two simple tags, one would be called {% domready %}, and another one is {% domready_render %}, first will add some js to some buffer and second will just join it alltogather and print it (at base template in some $(document).ready(...)). So my question is: where/how do I need to store some variables between those tags? (maybe some current request context or what?) 

I mean, I wrote something like:

@register.tag

def domready(parser, token):

    nodelist = parser.parse(('enddomready',))

    parser.delete_first_token()

    return DomreadyNode(nodelist)

class DomreadyNode(template.Node):

    def __init__(self, nodelist):

        self.nodelist = nodelist

        

    def render(self, context):

        if 'dom_ready' not in context:

            context['dom_ready'] = []

        

        context['dom_ready'].append(self.nodelist.render(context))

        return ''

@register.tag

def domready_render(parser, token):

    return DomreadyRenderNode()

class DomreadyRenderNode(template.Node):

    def render(self, context):

        if 'dom_ready' in context:

            return u"\n".join(context['dom_ready'])

        return ''

But it doesn't work in different templates (contexts are different?).

Thank you.
