/*look for implementation of ApparecchioRent in project complex :

    - build a class just to have a model to collect some data from a form and run actions

    - add a form with fields for each model property, with custom width of the label container

    - style the form 

    - add validators and labels to model and control them from js in case of error

    - use a NumberControl instead of a simpler html input number

    - get visible rows from datatable and build an array with their ids

    - serialize the array of ids and assign it to a hidden field in the form

    - intercept beforeSubmit, launch loading animation and send the data

    - get data in php and deserialize the array of strings

    - run actions of update/save in db with try/catch 

    - send positive response from php to js or error msg in case of exceptions

    - display error msg in js or trigger datatable reload on positive response
