How to show pop on seleted text

Question

Above is the data table in which I am pulling data from database and displaying in different column. as shown in the screen. I want to show pop at every failed record which will show reason for failed record. but I am confuse how do I do that.since all the data are dynamic how do i select the that data. for an example 121 ,2 and 72 are failed, so I need to show a pop after clicking on 121,2 and 72. As we can see in failed column we have 0 also. then if user click on zero it should not allow to open popup. list is dynamic I can get more than 100 failed records. so at every failed records I need to show pop.

Popup would have table containing four columns. for an example a b c d.

 1. How do I identify `121` `2` `72` or any other failed record.
 2. How do I show a pop-up after clicking on failed records.

this is the code for Data Table

  var oTable = 	$('#example')
    .dataTable(
    		{
    		"processing" : true,
    		"serverSide": true,
    	    "autoWidth" : true,
    		"order": [[ 0, "desc" ]],
    		"ajax" : {
    				"url" : '//myurl',
    				"dataSrc" : ""
    				},
    				"columns" : [			
    																					
    							{
    							  "data" : "recordcount"
    							},									
    							{
    							  "data" : "record failed"
    ]							}	
}
    				

Since we are getting the data in compact form. how to know which are failed.

I am beginner, trying to learn new things. I dint have any idea how to achieve this. please help me.
