.x-grid-row  .x-grid-tree-node-expanded {
    background: url('http://icons.iconarchive.com/icons/sekkyumu/developpers/16/Play-Green-Button-icon.png') no-repeat center center !important;
}
.x-grid-row  .x-grid-tree-node-leaf {
    background-image:url('http://icons.iconarchive.com/icons/graphicrating/koloria/16/Button-Play-Pause-icon.png');
}

How can i do that thanks

You haven't override the right css classes. Here is what you need:

.x-grid-tree-node-expanded .x-tree-icon-parent {
    background: url('http://icons.iconarchive.com/icons/sekkyumu/developpers/16/Play-Green-Button-icon.png') no-repeat center center !important;
}
.x-grid-row  .x-tree-icon-leaf {
    background-image:url('http://icons.iconarchive.com/icons/graphicrating/koloria/16/Button-Play-Pause-icon.png');
}

And the updated jsfiddle.
