I'm trying to hook up a checkbox to my View, but as soon as I tick it, it stays checked, even when I click it again?

Here's part of the View:

views.PaginatedView = Backbone.View.extend({
    events: {
        'click inputpletedEnquiries': 'filterCompletedEnquiries'
    },
    filterCompletedEnquiries: function (e) {
        return e.currentTarget.checked;
    }
});

Heres the template:

<label>Show Completed: <input type="checkbox" class="pletedEnquiries" /></label>

I've no idea what I'm doing wrong here?

Edit

Here is a Jsfiddle of the problem: /

• Something else is happening due everything looks right for me. Can you reproduce the issue in a jsFiddle? – fguillen Commented Aug 30, 2012 at 11:20

The problem is returning e.currentTarget.checked from your event handler. Returning true or false from this handler will check or uncheck the box for you

 filterCompletedEnquiries: function(e) {
        //return e.currentTarget.checked;
    },

ment out that return statement, and it works fine. You can still grab the info, but don't return anything from the method.

 filterCompletedEnquiries: function(e) {
        var isChecked = e.currentTarget.checked;
        // do stuff here, based on it being checked or not
    },

Edit

Here's an example, based on the conversation in the ments:

views.PaginatedView = Backbone.View.extend({
    events: {
        'click input.pletedEnquiries': 'pletedEnquiriesClicked'
    },

    // this is explicitly an event handler, and that's all it should be used for
    pletedEnquiriesClicked: function(e){
      this.showCompletedEnquiries = e.currentTarget.checked;
    },

    doSomething Else: function (e) {
        // now that we need to know, we can just check that attribute
        if (this.showCompletedEnquiries){
          // do something here
        }
    }
});

This is just one of many options you have, for making this work the way you want.
