How to create new link to run a function

[RahulSwami01]

i was trying to understand this link, but not sure how the link is created.
directory_table_list.html

a href="{{ file.get_admin_delete_url }}{% filer_admin_context_url_params %}" title="{% translate 'Remove file' %}" class="action-button"></a

How above link is executing this function: fileadmin.py
def delete_view(self, request, object_id, extra_context=None):

When i create a similar function like get_admin_run_url I get error.
a href="{{ file.get_admin_run_url }}" title="{% translate 'Run file' %}" class="action-button" onclick="{% runfile %}"></a

filemodels.py
def get_admin_run_url(self):
return self.get_admin_url("run")

ERROR:-
