I recently upgraded from pqGridPro 2.2.0 to 2.4.1, and I think that there is a bug related to editModel.clicksToEdit. In pqGridPro 2.2.0 I found that setting editModel.clicksToEdit:1 works correctly. However, in pqGridPro2.4.0 and up, I found that regardless of the setting for editModel.clicksToEdit, it is always necessary to click TWICE in order to send the cell into edit mode, even if editModel.clicksToEdit:1. There is no onclick event for the column or the row or the cell or the contents of the cell, so none of that is causing the strange behavior; it appears to be a problem with pqGridPro.
