Dynamically Adding And Removing Checkbox - Linked Cells

I have problems with dynamically adding and removing checkboxes. I have a form and there is a button to add more rows to the table. Every row includes a checkbox too.

So first i add a row, and then add a checkbox to a specified cell in that row.There is a button for removing rows as well (witch should removes checkboxes as well).

My problem is when i ad the checkbox the linked cell property only works for the first one.When i add the second row the linked cell of the firstly added checkbox changes to the one in the new row and the new checkbox has no linked cell. I am adding the stuffs as follows:

VB:
Private Sub addBtn_Click()
Dim y As Integer
y = findFunc("end") // Y define where To insert the New row
Cells(y, 11).EntireRow.Insert
Cells(8, 11).Copy

[Code] .....

Any way to add checkboxes dynamically.
