How to change the icon label Yandex map when the mouse is over a list of objects?

In Yandex.Maps has the ability to set your icon label and have the opportunity to change the standard icon of a label when the event card. Alas, I can not figure out how to change my icon to another when an external event. Specifically: how to change the value iconImageHref for example here:

myPlacemark = new ymaps.Placemark(myMap.getCenter(), {
 hintContent: 'Own icon label'
 }, {
 iconLayout: 'default#image',

 // This value needs to be changed after adding markers on a map
 iconImageHref: 'examples/maps/ru/icon_customImage/images/myIcon.gif',

 iconImageSize: [30, 42],
 iconImageOffset: [-3, -42]

Hover over the words "hover me", the icon will change, and will change back when you remove the mouse.
