ArcPy to select by location not showing selected features in attribute table

Question

I have a button where it first calculate no of features in a specific layer and then runs the "are_identical_to" and update "D". After that it checks if the no of counts in two layers is same? If not, then runs the "are_identical_to" on two different layers and should show up the selected features in my data frame.

However it never shows the selected features in data frame or attribute table?

How can I achieve this.

code is shown below:

import arcpy
import pythonaddins
class Check1(object):
 """Implementation for Preproduction_Check_addin.Check1 (Button)"""
 def __init__(self):
 self.enabled = True
 self.checked = False
 def onClick(self):
 lyr1 = ""
 lyr2 = ""
 lyr3 = ""
 result2 = ""
 result3 = ""
 count2 = ""
 count3 = ""
 mxd = arcpy.mapping.MapDocument("CURRENT")
 layers = arcpy.mapping.ListLayers(mxd)
 for layer in layers:
 if layer.isFeatureLayer and layer.workspacePath != "":
 if "edits" in layer.name:
 lyr1 = layer
 elif "fresh" in layer.name:
 lyr2 = layer
 result2 = arcpy.GetCount_management(lyr2.dataSource)
 count2 = int(result2.getOutput(0))
 print("Total Features in fresh data:")
 print(count2)
 elif "D" in layer.name:
 lyr3 = layer
 Selection = arcpy.SelectLayerByLocation_management(lyr1, "ARE_IDENTICAL_TO", lyr2)
 if arcpy.Describe(lyr1.name).FIDSet:
 with arcpy.da.UpdateCursor(lyr1.name, "Update") as curs:
 for row in curs:
 row = ("D",)
 curs.updateRow(row)
 del curs
 del row
 print("Remark 'D' Updated")
 result3 = arcpy.GetCount_management(lyr3.dataSource)
 count3 = int(result3.getOutput(0))
 print("Total features in 'D' Layer:")
 print(count3)
 if count3 == count2:
 print("Everything OK!, Please continue.")
 else:
 Selection = arcpy.SelectLayerByLocation_management(lyr1, "ARE_IDENTICAL_TO", lyr3,0,"SWITCH_SELECTION")
 print("Some features not matched, Please review.")

Try adding arcpy.RefreshActiveView() after applying the selection.
