How can I intercept the Update button press on the popup editor?

I don't like using the Html Model "For" helpers, instead I'm a bit old school where I use javascript to populate my form before it shows.  Because of this, when I Add or Edit a record, obviously the model isnt populated with the form field values.  So how I can detect when the Update button was pressed for either an Add or Edit, and so I can collect the values programmatically to pass to the MVC action for Edit / Create?

Hi Joe,

Have in mind that that the names of the inputs must match the names of the properties of the data model. If they match, all fields of the model will bind automatically to the values of the inputs.

However, possible solution to manually set the values is to add event handler to the input and when it changes, change the value in the model:

Attach event handler:

.Events(x=> x.Edit("onEdit"))

Event handler logic:

 
function onEdit(e) {
 
    e.container.find('#nameOfField').on('change', function () {
             
        e.model.set("nameOfField", this.value);
        console.log(e.model);
    })
}

Attached you will find a small sample illustrating the aforementioned approach.
