    element.prop(properties)

Set properties, possibly nested, on the element model. This is an equivalent of the attr() method but this time for custom data properties.

    element.prop('name/first', 'John')
    element.prop('name/first')  // 'John'
    element.prop({ name: { first: 'John' } })
    // Nested arrays are supported too:
    element.prop('mylist/0/data/0/value', 50)
    element.prop({ mylist: [ { data: [ { value: 50 } ] } ] })
