Is it possible to remove a model by cid? - backbone.js

Question

I have a view called Entry.
class Movieseat.Views.Entry extends Backbone.View
template: JST['movieseats/entry']
className: 'movie-frame'
initialize: ->
#collection.on('change', #render, this)
#collection.on('remove', #render, this)
render: ->
$(#el).html(#template(entry: #collection))
this
events: ->
"click .remove": "removeEntry"
removeEntry: (e) ->
console.log #collection
This view creates a Entries template.
<div data-id="<%= #entry.get('id') %>">
<p><%= #entry.get('title') %></p>
<p><%= #entry.get('id') %></p>
<p class="remove">Remove</p>
</div>
What I want to do is to remove a model from the collection (movieseats) and then rerender the template. If I click on a entry I fire the console.log #collection event. This logs the following,
Backbone.Model {cid: "c4", attributes: Object, collection: Movieseats, _changing: false, _previousAttributes: Object…}
How would I target the model's cid and then remove it from the collection?
Update
If I use this code,
removeEntry: (e) ->
thisid = $(e.currentTarget).closest('div').data('id')
console.log #collection
modelToRemove = #collection.findWhere({cid: thisid });
#collection.remove(modelToRemove);
I get the following result in the console log.
Backbone.Model {cid: "c4", attributes: Object, collection: Movieseats, _changing: false, _previousAttributes: Object…}_changing: false_events: Object_pending: false_previousAttributes: Objectattributes: Objectchanged: Objectcid: "c4"collection: Movieseatsid: 531__proto__: Object
Uncaught TypeError: undefined is not a function
The problem seems to be this part,
modelToRemove = this.collection

You can do it using this code (see collection#remove method):
var modelToRemove = collection.findWhere({cid: "SOME_ID_HERE"});
collection.remove(modelToRemove);
See also findwhere docs.
Edit
From the output of the console.log method it appears that the #collection variable in your above code is not a true Backbone.Collection, but rather a model pointing to the collection. Thus, you should modify the above code to be:
trueCollection = #collection.get("collection") // or #collection.collection
modelToRemove = trueCollection.findWhere( cid: "SOME_ID_HERE" )
trueCollection.remove(modelToRemove)
