Dynamic onClick and passing a parameter to the function??

Hi,

I am trying to change the onClick of this button dynamically.  Initially the button says "edit", when you click "edit" I redefine some of the properties of the button

function editFunction(currentRow, someId) {
       editButton.id = 'btnSave' + currentRow;
      editButton.name = 'btnSave' + currentRow;
      editButton.value = 'Save';
      editButton.onclick = saveFunction;

}

function saveFunction(someId) {
alert(someId)
}

Hope that makes sense, basically I am just trying to get the variable which is passed into editFunction() to be available to the saveFunction.
