Can't get the text from LineEdit to pass to a function - godot

Question

Context:
I click on a button -> a WindowDialogue appears -> there are 2 LineEdit Nodes and a button
Supposed procedure:
I fill these LineEdits, press the button, and the function tied to the button receives the texts from the LineEdits (and creates a dictionary key-value pair).
Problem:
The texts from the LineEdits do not pass down to the function (through connect()).
I tried passing the text directly with LineEdit.text. I tried writing it in a different variable and passing the variable. The debug shows the function is getting executed (no problem with that), but the strings passed from the LineEdits are always empty. Somehow, it worked for some time when I explicitly pressed ENTER after filling the LineEdits. But after I tried to fix the aforementioned problem, it stopped working altogether.
P.S. Everything I mentioned is created dynamically through the code, if that matters.
Code:
#Declaring the variables
var temp_text_key = ""
var temp_text_value = ""
#Function to show up a dialogue window with LineEdits and Confirm button
func _on_add_new_property(dict: Dictionary):
temporal_window_dialogue = WindowDialog.new()
temporal_window_dialogue.rect_min_size = Vector2(410,90)
temporal_window_dialogue.resizable = true
temporal_window_dialogue.popup_exclusive = true
temporal_window_dialogue.window_title = "Adding new property to %s" % get_dict_name_by_id(professions, dict["id"])
var le_key = LineEdit.new()
le_key.placeholder_text = "Name of the property"
le_key.hint_tooltip = "Name of the property"
le_key.connect("text_changed", self, "_on_add_new_prop_text_entered", ["key"])
var le_value = LineEdit.new()
le_value.expand_to_text_length = true
le_value.placeholder_text = "Value of the property"

You mentioned using 'LineEdit.text', but have you tried the following?
var text = LineEdit.get_text()
If this doesn't help, please update your original post to include code examples.
