Column '{colId}' template sets '{attr}'. Inline event handlers are not allowed in templates; use grid events or a component renderer. The attribute was dropped.

Since

1.0.1

What happened

An on… attribute in a cell template is an inline event handler, which would execute template-authored code on every paint. The attribute is dropped; the element is still rendered without it, so the cell looks right and does nothing when clicked.

The fix

Listen for the grid's own cell events, or use a component renderer that attaches its own listeners.

The smallest fix

grid.on('cell:click', ({ key, colId }) => open(key, colId));
