Knockoutjs computed passing parameters

Question

I am wondering if it is possible with knockoutjs to pass arguments when binding.

I am binding a list of checkboxes and would like to bind to a single computed observabl

Without knowing the specifics, it seems like what you should be doing is defining a ko.observableArray or computed array value

HTML:

myprop: 

  
    
    
  

JS:

  $(function() {
    function Model() {
        this.self = this
        self.myprop = ko.observable(14)
        self.bits = [1, 2, 4, 8, 16, 32, 64, 128]
        self.selections = ko.computed(function() {
            return self.bits.map(function(bit) {
                console.log(myprop() & bit)
                return {
                    value: bit,
                    selected: (myprop() & bit) == bit
                }
            })
        })
    }

    ko.applyBindings(new Model())
})

and not passing values from the markup to define the model state
