I'll tried to use this with a model that has a nested tree relationship. The model form contains a list of children, where you can create a child using a button. This opens the create modal for the child modal, but does not handle the deferred bindings. Thus when creating the child record using the modal, it has no parent_id.

Please check your functionality on the new version of the plugin. Added support for the transfer of multiple parameters for controller (/:id/:secondArg/:thirdArg) from events on buttons. Used variable list from $controller->listConfig->recordUrl

Added on v1.1.0:

• Added support change modal popup size for all buttons (exclusion "Create" button on topbar - default 'giant', no change size... in other relises..)
• Added support for the transfer of multiple parameters for controller ( /:id/:secondArg/:thirdArg, tested on "janvince/smallrecords" plugin)
• Added multiple controller config lists supports (tested on "janvince/smallrecords" plugin)
• Added support onCreate event button on form
• New extended configutation settings for default and individual settings for controllers
• Added backend, cms, system controllers lists support ("Administrators", "Event log" controllers - correct works only on BackendPopup partials)
• Added BackendPopup "update" and "create" partials
• Added settings for "create" partial in individual settings
• Added the ability to disable the functionality of BackendPopup for the selected controller in the individual settings.
