DatePickerSingle - Dynamic

Hey,

I have a question, I am developing an analytic tool and i am stuck with the DatePickerSingle.
Indeed, I have a data set of 1500 rows with each row a column called date with this format : ‘13 Jan 2017’.
all the data set is now in a dataframe.
However, i would like to click on a specific date and display the data from the dataframe that contain this date.

For the moment I have this code :

Can someone tell me where I am missing something ?
Thank you very much and have a nice day.

Jordy.
