How do I programmatically add a button to a gridview and assign it to a specific code-behind function?

In runtime I’m creating a DataTable and using nested for-loops to populate the table. This table I later assign as DataSource to a gridview and on RowDataBound I assign the value of each cell. I want to know how I can give each cell a button and assign that button to a codebehind function. I’ll have 12 buttons and each one will contain a different value. I would prefer if they all call the same function with some kind of event that stores the cell-specific value.
