Pouchdb query not filtering KEY when turning on the device

Hello I have this pouchdb query:

function(test, key){
        var temp = [0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0];
        var day = [];

        $q.when(cigdb.query('learnIndex/by_data_type',{key: key, include_docs : true})).then(function(res){
                $q.all(res.rows.map(function(row){
                    console.log(row.doc);
                    day.push(row.doc.day);
                    return temp[row.doc.hour]++;
            }));
        }).then(function(te){
            day = day.unique();
            console.log(day);
            test.splice(0,24);
            for(var i = 0; i<24; i++){
                if(day.length > 0){
                    test.push(temp[i]/day.length);
                }else{                    
                    test.push(temp[i]);
                }
            }
            console.log(test);
            return test;
        }).catch(function(err){
            console.log(err); 
        }); 
    },

which works well on the browser but when debugging it on the device (android) it jumps part of the code.

On the device it executes until the $q.all(...) then it ignores completely the block :

 console.log(row.doc);
 day.push(row.doc.day);
 return temp[row.doc.hour]++;

And keeps going executing the promise .then(function(te) as nothing was wrong

obs: my first work with js angular and ionic not really familiar with that

Thanks for any help

edit: I already did try whith Promise.all(...) and putting a return before $q.all(...) and Promise.all(...)

and on all of then did work on the browser but on the device the problem was the same.

edit2 : so after diging a bit if i send on console.log(res) just before $q.all() it returns :

Object {total_rows: 32, offset: 0, rows: Array[0]}
offset: 0
rows:    Array[0]
total_rows: 32
__proto__: Object

while on the browser i have:

Object {total_rows: 11, offset: 0, rows: Array[10]}
offset: 0
rows: Array[10]
total_rows: 11
__proto__: Object

for some reason pouchdb is not populating the row

edit3:

changing the code:

q.when(cigdb.query('learnIndex/by_data_type',{key: key, include_docs : true})).then(function(res){
                $q.all(res.rows.map(function(row){
                    day.push(row.doc.day);
                    return temp[row.doc.hour]++;
            }));

for :

$q.when(cigdb.query('learnIndex/by_data_type',{include_docs : true})).then(function(res){
                return $q.all(res.rows.map(function(row){
                    if(row.doc.data_type === key){
                    day.push(row.doc.day);
                    return temp[row.doc.hour]++;
                    }
                }));

makes it work but now i dont get why the key is not filtering as supposed on de device what makes the query useless as i could use a simple alldocs if i have to implement the filtering any way.
