useEvents High Order Hook/Function for separation of template and logic in React
/* events should be an object containing DOM event names as keys (click, keyup, hover...), with the values as objects having
* element "names" as keys, and event handler functions as values. E.g.:
* {
* click: {
* button1() { // handle button1 click },
* button2() { // handle button2 click },
* keyup {
* input1() { // handle input1 keyup }
* }
* }
* Note that you need to assign names to elements you'd like their triggered events to be handled, by using a data-name attribute.
