knockout.js - Does afterRender work with Knockout components?

afterRender works with template bindings, but after converting my templates to components, there does not seem to be any way to use afterRender. I have tried looking for an example of a component that uses afterRender, but cannot find anything.

I could not get the method working as per the above post. However i found a workaround on the git issue list and it doesn't require a custom KO Binding.

Add the below line in your component template html or string of code.

 <span data-bind="template: { afterRender: init }"></span>

Then create a init function in your module / viewModel:

 this.init = function() {
   Do cool DOM stuff here.
}

or depending on your viewModel structure:

viewModel: function(params) {
    return {
        init: function () {

        }
    };
},

Works like a charm. Example of it working is here

Thread on knockout git here: https://github.com/knockout/knockout/issues/1533

Thanks to vamps on git for the workaround.
