does mapping plugin create dependencies?

[Juan Pablo Ramírez]

Hello all.

I have an example of code, where I am trying to call an ajax function, like this:

var data = { . . .
    filter: {
        param1: ko.observable(),
        param2: ko.observable(),
        . . .
        paramN: ko.observable()
    }
}


function ViewModel() {

    var self = this;

    self.sendData = function() {
        $.ajax("address", ko.mapping.toJS(data.filter)).done(function() { . . . })
    }
}

data.filter observables are binded with many text fields in html.

ViewModel.sendData function will be called only by a click binding in a button, but my code is calling it whenever a data.filter changes.

On the one hand, is there a method to avoid ko.mapping.toJS create any dependencies?

On the other hand, ViewModel.sendData function is not an observable, but, I have read ko transforms functions into computed's. I tried to avoid it by including model and event parameters into its signature, but I can't get the solution.

Can you give me a hand with this, please?

Thanks a lot in advance.
