Need to plugin custom filters and behaviour while using that filter

[sarvabowmen]

First of All, Thanks for the super cool multi-select plugin. I have some requirements using bootstrap multi-select, I am achieving that using my custom code instead of plugging in my code into the bootstrap multiselect.

We have an option to assign the filter template using the templates option, but it doesn't have any property or event where i can plugin my custom code which will be executed when i click on the filter. It would be great if we have any options for that.

Related to #543, #408.

You mean a hook/callback whenever the shown options are updated, i.e. the user filters the options?
