onClick not propagated - html

Question

I'm having troubles with creating a simple gallery allowing to print pictures. I constructed the interface. When I click on the print button, I'm not able to propagate event to a function. Funny enough, it always works for just a couple of items in the gallery so that console logs foo. Could you please point me where is the problem? I am using material-ui, tileData is a json with image url etc...
Many thanks!
class Galery extends React.Component {
state = {
tileData: tileData
};
printThis = tile => {
console.log("printing tile... " + tile.target.value);
};
render() {
const classes = this.props;
return (
<div className={classes.root}>
<ButtonAppBar />
<div style={{ marginBottom: 20 }} />
<Grid container spacing={8}>
<Grid item xs={10}>
<GridList
cellHeight={250}
cellWidth={250}
cols={5}
spacing={4}
className={classes.gridList}
>
{tileData.map(tile => (
<GridListTile key={tile.img}>
<img src={tile.img} alt={tile.title} />
<GridListTileBar
title={tile.title}
subtitle={<span>by: {tile.author}</span>}
actionIcon={
<IconButton
className={classes.icon}
value="foo"
onClick={this.printThis}
>
<i className="material-icons md-24 md-light">print</i>
</IconButton>
}
secondActionIcon={
<IconButton className={classes.icon}>
<i className="material-icons md-24 md-light">delete</i>
</IconButton>
}
/>
</GridListTile>
))}
</GridList>
</Grid>
<Grid item xs={2}>
<div className={classes.stats}>
<StatsTable />
</div>
</Grid>
</Grid>
</div>
);
}
}

It works for me to access the object id through event.currentTarget as per github answer here https://github.com/mui-org/material-ui/issues/7974#issuecomment-329250974
`
So my implementation is:
printThis = (event) => {
console.log('printing tile... '+ event.currentTarget.id);
};
<IconButton className={classes.icon} id = {tile.img} onClick={this.printThis}>
<i className="material-icons md-24 md-light" >
print
</i>
</IconButton>
