Date "less but not empty" custom search in free-jqgrid - jqgrid

Question

I am using free-jqgrid 4.15.4 for showing the data. There i have a need to search date column with Date less but not empty filter, but it is not filtering correctly. In result it gives me date which are greater than searched date.
Below code is used for custom filter in date column:
customSortOperations: {
dlne: {
operand: "<!=''",
text: "Date less but not empty",
filter:function (options) {
var p = this.p, iCol = p.iColByName[options.cmName], cm = p.colModel[iCol],
newformat = cm.formatoptions != null && cm.formatoptions.newformat ?
cm.formatoptions.newformat :
$(this).jqGrid("getGridRes", "formatter.date.newformat"),
srcformat = cm.formatoptions != null && cm.formatoptions.srcformat ?
cm.formatoptions.srcformat :
$(this).jqGrid("getGridRes", "formatter.date.srcformat"),
fieldData = $.jgrid.parseDate.call(this, srcformat, options.item[options.cmName]),
searchValue = $.jgrid.parseDate.call(this, newformat, options.searchValue);
var retFData = convertD(fieldData), t = new Date(retFData);
if ((retFData.getFullYear() < searchValue.getFullYear()) && (retFData.getMonth() < searchValue.getMonth()) && (retFData.getDate() < searchValue.getDate())) {
return true
}
}
},
}
The convert function that I am using for converting string into date format, is written below:
function convertD(dateField) {
var date = new Date(dateField),
mnth = ("0" + (date.getMonth() + 1)).slice(-2),
day = ("0" + date.getDate()).slice(-2);
// year= (date.getFullYear())
var retVal = [day, mnth, date.getFullYear()].join("/");
return retVal;
}
I have taken the idea from here and made some changes but seems no avail. So requesting community to help on this.

The code of dlne could be fixed to for example the following:
dlne: {
operand: "<!=''",
text: "Date less but not empty",
filter: function (options) {
var p = this.p, iCol = p.iColByName[options.cmName], cm = p.colModel[iCol],
newformat = cm.formatoptions != null && cm.formatoptions.newformat ?
cm.formatoptions.newformat :
$(this).jqGrid("getGridRes", "formatter.date.newformat"),
srcformat = cm.formatoptions != null && cm.formatoptions.srcformat ?
cm.formatoptions.srcformat :
$(this).jqGrid("getGridRes", "formatter.date.srcformat"),
fieldData, searchValue;
// the exact condition to test for "empty" depend on the format of your data
if (!options.item[options.cmName]) {
return false; // ignore empty data
}
fieldData = $.jgrid.parseDate.call(this, srcformat, options.item[options.cmName]);
searchValue = $.jgrid.parseDate.call(this, newformat, options.searchValue);
return fieldData.getFullYear() < searchValue.getFullYear() ||
(fieldData.getFullYear() === searchValue.getFullYear() &&
fieldData.getMonth() < searchValue.getMonth()) ||
(fieldData.getFullYear() === searchValue.getFullYear() &&
fieldData.getMonth() === searchValue.getMonth() &&
fieldData.getDate() < searchValue.getDate());
}
}
