How to ModelBind to ASP.net MVC and Datasource Model

[axwack]

I am trying to use MVC's model binding functionality. I have  a source that I need to submit to the server and then have it return a value called a Yield to Maturity. The issue is my form is bound to a viewModel. When I do a yieldSource.sync() , the form is submitted with my schema model but nothing is populated. 

Here is my code: Originally I was doing gets in the addYieldValues method but that didn't seem to do anything unless I put the values in an array.

Please help.

$(document).ready(function () {

        

           var viewModel = kendo.observable({

            

           order : {

                               return this.get("UnderlyingPar") * (this.get("UnderlyingPrice")/100) + this.get("UpfrontFees");

Hi,

The MVC model binder will not be able to parse the data in the used format. I can suggest to check this code library which demonstrates how to format the parameters in the parameterMap function.
